英文原文:Mechanical properties of materialsThe material properties can be classified into three major headings: 1 physical; 2 chemical; 3 mechanicalPhysical propertiesDensity or specific gravity; moisture content; etc.; can be classified under this category.Chemical propertiesMany chemical properties come under this category. These include acidity or alkalinity; react6ivity and corrosion. The most important of these is corrosion which can be explained in layman’s terms as the resistance of the material to decay while in continuous use in a particular atmosphere.Mechanical propertiesMechanical properties include in the strength properties like tensile; compression; shear; torsion; impact; fatigue and creep. The tensile strength of a material is obtained by dividing the maximum load; which the specimen bears by the area of cross-section of the specimen.. Within the elastic range; the limiting value of the stress up to which the stress and strain are proportional; is called the limit of proportionality Ap. In this region; the metal obeys hookes’s law; which states that the stress is proportional to strain in the elastic rangeof loading; the material completely regains its original dimensions after the load is removed. In the actual plotting of the curve; the proportionality limit is obtained at a slightly lower value of the load than theelastic limit. This may be attributed to the time-lagin the regaining of the original dimensions of the material. This effect is very frequently noticed in some non-ferrous metals.Which iron and nickel exhibit clear ranges of elasticity; copper; zinc; tin; are found to be imperfectly elastic even at relatively low values low values of stresses. Actually the elastic limit is distinguishable from the proportionality limit more clearly depending upon the sensitivity of the measuring instrument.When the load is increased beyond the elastic limit; plastic deformation starts. Simultaneously the specimen gets work-hardened.A point is reached when the deformation starts to occur more rapidly than the increasing load. This point is called they yield point Q. the metal which was resisting the load till then; starts to deform somewhat rapidly; i. e.; yield. The yield stress is called yield limit Ay.The elongation of the specimen continues from Q to S and then to T. The stress-strain relation in this plastic flow period is indicated by the portion QRST of the curve. At the specimen breaks; and this load is called the breaking load. The value of the maximum load S divided by the original cross-sectional area of the specimen is referred to as the ultimate tensile strength of the metal or simply the tensile strength Au.Logically speaking; once the elastic limit is exceeded; the metal should start to yield; and finally break; without any increase in the value of stress. But the curve records an increased stress even after the elastic limit is exceeded. Two reasons can be given for this behavior:①The strain hardening of the material;②The diminishing cross-sectional area of the specimen; suffered on account of the plastic deformation.The more plastic deformation the metal undergoes; the harder it becomes; due to work-hardening. The more the metal gets elongated themore its diameter and hence; cross-sectional area is decreased. This continues until the point S is reached.After S; the rate at which the reduction in area takes place; exceeds the rate at which the stress increases. Strain becomes so high that the reduction in area begins to produce a localized effect at some point. This is called necking.Reduction in cross-sectional area takes place very rapidly; so rapidly that the load value actually drops. This is indicated by ST. failure occurs at this point T.Then percentage elongation A and reduction in reduction in area W indicate the ductility or plasticity of the material:A=L-L0/L0100%W=A0-A/A0100%Where L0 and L are the original and the final length of the specimen;A0 and A are the original and the final cross-section area.The Two Types Of Power TransmissionIn hydraulic power transmission the apparatus pump used for conversion of the mechanical or electrical;thermal energy to hydraulic energy is arranged on the input of the kinematic chain ;and the apparatus motor used for conversion of the hydraulic energy to mechanical energy is arranged on the output fig.2-1The theoretical design of the energy converters depends on thecomponent of the bernouilli equation to be used for hydraulic power transmission.In systerms where; mainly; hydrostatic pressure is utilized;displacement hydrostatic pumps and motors are used; while in those where the hydrodynamic pressure is utilized is utilized gor power transmission hydrodynamic energy converters e.g. centrifugal pumps are used.The specific characteristic of the energy converters is the weight required for transmission of unit power. It can be demonstrated that the use of hydrostatic energy converters for the low and medium powers;and of hydrodynamic energy converters of high power are more favorite fig.2-2. This is the main reason why hydrostatic energy converters are used in industrial apparatus. transformation of the energy in hydraulic transmission.1.driving motor electric; diesel engine;2.mechanical energy;3.pump;4.hydraulic energy;5.hydraulic motor;6.mechanical energy;7.load variation of the mass per unit power in hydrostatic andhydrodynamic energy converters1、hydrostatic; 2.hydrodynamicOnly displacement energy converters are dealt with in the following. The elements performing converters provide one or several size. Expansion of the working chambers in a pump is produced by the external energy admitted; and in the motor by the hydraulic energy. Inflow of the fluid occurs during expansion of the working chamber; while the outflow displacement is realized during contraction. Such devices are usually called displacement energy converters.The Hydrostatic PowerIn order to have a fluid of volume V1 flowing in a vessel at pressure work spent on compression W1 and transfer of the process; let us imagine a piston mechanism fig.2-3a which may be connected with the aid of valves Z0 and Z1 to the external medium under pressure P0 and reservoir of pressure p1.in the upper position of the piston x=x0 with Z0 open the cylinder chamber is filled with fluid of volume V0 and pressure P0. now shut the value Z0 and start the piston moving downwards. If Z1 is shut the fluid volume in position X=X1 of the piston decreases from V0 to V1; while the pressure rises to P1. the external work required for actuation of the piston assuming isothermal change isW1=-∫0x0P-P0Adx=-∫v1v0P-P0dv译文:材料的机械性能材料的机械性能可以被分成三个方面：物理性能;化学性能;机械性能..物理性能密度或比重、温度等可以归为这一类..化学性能这一种类包括很多化学性能..其中包括酸碱性、化学反应性、腐蚀性..其中最重要的是腐蚀性;在外行人看来;腐蚀性被解释为在某处的零件抵抗腐蚀的能力..机械性能机械性能包括拉伸性能、压缩性能、剪切性能、扭转性能、冲击性能、疲劳性能和蠕变..材料的拉伸强度可以通过试件的横截面积出试件承受的最大载荷得到;这是在拉伸试验中;应力沿Y轴;应边沿X轴变化的曲线..一种材料加载时开始发生变化的初值取决于负载的大小..当负载去掉时可以看到变形消失..对于很多材料而言;在达到弹性极限的一定应力值A之前;一直表现为这样..在应力--应变图中;这是可以用线性关系来描述的..这之后又一个小的偏移..在弹性范围内;达到应力的极限之前;应力和应变是成比例的;这被称为比例极限Ap..在这个区域;零件符合胡克定律;即应力与应变是成比例的;在弹性范围内材料能完全恢复到最初的尺寸;当负载去掉时..曲线中的实际点;比例极限在弹性极限处..这可以认为是材料恢复初值时落后于前者..这种影响在不含铁的材料中经常提到..铁和镍有明显的弹性范围;而铜、锌、锡等;即使在相对低的应力下也表现为不完全弹性..实际上;能否清楚地分辩弹性极限和比例极限取决于测量设备的灵敏度..当负载超过弹性极限时;塑性变形开始;逐渐的试件被硬化..变形比负载增加得更快时的点被称成为屈服点Q..金属开始抵抗负载转变成快速变形;这时的屈服力成为屈服极限Ay..试件的延伸率继续由Q到T再到;在这种塑性流动时;应力—应变关系在曲线上处于QRST区域..在点;试件破坏且这种负载称为破坏负载..最大负载S除以试件初始的截面积;被定义为这种金属的最终拉伸极限或试样的拉伸强度Au..按逻辑说;在应力不增加的情况下;一旦超出弹性极限;金属开始屈服;并最终破坏..但是当超出弹性极限后;在纪录曲线上应增大..这种变化主要有两个原因：①材料的应力硬化②由于塑性变形而引起的试件横截面积的变小由于加工硬化;金属塑性变化越大;硬化越严重..金属拉伸越长;他的直径横截面积越小..直到到达点为止..点之后;减少的速率开始变化;超过了应力增加的速率;应变很大以至于在局部的某些点的面积减少;被称为颈缩..横截面积减少得非常快;以至于抗负载的能力下降;即ST阶段..破坏发生在T点..延伸率A和截面积变化率u被描述成材料的延展性和塑性：a=L0-L/L0100%u=A0-A/A0100%在这里;L0和L分别是试件的最初和最终长度;A0和A分别是试件的最初截面积和最终截面积..动力传动的两种类型在液力传动中;用来将机械能电能、化学能转化成液力能的装置泵被布置在传动链的输入端;而用来将液力能转化成机械能的装置马达被布置在输出端..图2-1这种能量转化的理论上的设计依据是液力传动的各部分的伯努里方程..在系统中;流体静压力主要用来替代泵和马达;而在某些方面;流体动力是作为液力能转化后的力传动而被利用的如离心泵这种能量转换的特征取决于单位力的传动..他能说明这种微小力的液体静压力能转换和高压力的液体动力能转换更受人们的欢迎..图2-2者是液力转换被应用于工业器械的主要原因..液力传动的能量转换 1、原动机电机、内燃机 2、机械能 3、泵 4、液力能5、液压马达 6、机械能 7、负载在流体静力能和流体动力能中单位里的质量变化替代能量转换仅应用以下几方面;在液体静压力转换中相关的替代执行元件提供一个或数个工作室;他们恒定或尺寸可变..泵的工作室在外部能量进入时伸长;马达是靠液力能;工作是伸长时液体流入;而收缩时实现流体流出..这些装置通常被称为能量转换装置..液体充满一个体积为V1的容器;在压力P1下所作的功W是压缩功W1和改变液体的功W2组成的..为了分析这个过程;让我们假设一个活塞机构图2-3a;它是有两个阀Z0、Z1和贮液器连接而成;表面压力为P0;贮液器内部压力为 P1;活塞处于上部的X=X0处;Z0打开;液体充满体积为V0的汽缸;压力为 P0;现在关闭阀Z0;并且开始向下移动活塞;如果 Z1关闭;当活塞下降到 X=X1处时;液体体积由V0变为V1;此时压力升至P1;驱动活塞所作的外部功是假设热量改变W1=-∫X1X0P-P0Adx=-∫V1V0P-P0dv。

Unit 1 MetalsUnit 2 Selection of Construction Materials淬透性：指在规定条件下，决定钢材淬硬深度和硬度分布的特性。

即钢淬火时得到淬硬层深度大小的能力，它表示钢承受淬火的能力。

钢材淬透性好与差，常用淬硬层深度来表示。

淬硬层深度越大，则钢的淬透性越好。

钢的淬透性是钢材本身所固有的属性，它只取决于其本身的部因素，而与外部因素无关。

钢的淬透性主要取决于它的化学成分，特别是含增大淬透性的合金元素与晶粒度，加热温度和保温时间等因素有关。

淬透性好的钢材，可使钢件整个截面获得均匀一致的力学性能以与可选用钢件淬火应力小的淬火剂，以减少变形和开裂。

淬透性主要取决于其临界冷却速度的大小，而临界冷却速度则主要取决于过冷奥氏体的稳定性，影响奥氏体的稳定性主要是：1.化学成分的影响碳的影响是主要的，当C％小于1.2％时，随着奥氏体中碳浓度的提高，显著降低临界冷却速度，C曲线右移，钢的淬透性增大；当C％大于时，钢的冷却速度反而升高，C曲线左移，淬透性下降。

其次是合金元素的影响，除钴外，绝大多数合金元素溶入奥氏体后，均使C曲线右移，降低临界冷却速度，从而提高钢的淬透性。

2.奥氏体晶粒大小的影响奥氏体的实际晶粒度对钢的淬透性有较大的影响，粗大的奥氏体晶粒能使C曲线右移，降低了钢的临界冷却速度。

但晶粒粗大将增大钢的变形、开裂倾向和降低韧性。

3.奥氏体均匀程度的影响在相同冷度条件下，奥氏体成分越均匀，珠光体的形核率就越低，转变的孕育期增长，C曲线右移，临界冷却速度减慢，钢的淬透性越高。

4.钢的原始组织的影响钢的原始组织的粗细和分布对奥氏体的成分将有重大影响。

5.部分元素，例如Mn，Si等元素对提高淬透性能起到一定作用，但同时也会对钢材带来其他不利的影响。

可锻性(forgeability)金属具有热塑性，在加热状态(各种金属要求温度不同)，可以进行压力加工，称为具有可锻性。

可锻性：指金属材料在压力加工时，能改变形状而不产生裂纹的性能。

This is often done using computer-aided design (CAD) software, which allows engineers to create 3D models and simulate the behavior of the product under various conditions. Once the design is finalized, it is then sent for manufacturing.Manufacturing involves a variety of processes, including machining, casting, molding, and additive manufacturing. Each of these processes has its own advantages and limitations, and the choice of manufacturing method depends on the specific requirements of the product. Advanced manufacturing techniques, such as 3D printing, are also becoming more prevalent, offering new possibilities for design and production.Automation is another key aspect of modern manufacturing, with many processes being fully or partially automated. This includes the use of robots and machinery to perform repetitive tasks, as well as the implementation of advanced control systems to optimize production. Automation not only increases efficiency but also improves safety by reducing the need for manual labor inhazardous environments.Overall, mechanical design, manufacturing, and automation are essential components of modern industry, driving innovation and enabling the production of high-quality products in a cost-effective manner. As technology continues to advance, the role of these processes will only become more important in shaping the futureof manufacturing.当谈到机械设计、制造和自动化时，值得注意的是这些领域的发展也在不断受到数字化和智能化的影响。
