Unit 1 Metals金属绝对纯净的金属从来也没有被生产出来过。
即使绝对纯净的金属可以生产出来，工程师们对它们也并不会特别感兴趣，因为它们很柔软、脆弱。
实际应用中的金属往往都包含着一定数量的一种或多种外来金属或非金属元素，这些外来元素可能是有害的也可能是有益的或者它们对某种特定的属性没有影响。
如果是有害the crystals of the various grains are ran domly orie nted in space. The gra ins are everywhere in in timate con tact with oneanother and joined together on an atomic scale. The region at which they join is known as a grain boun dary.An absolutely pure metal (i.e. one composed of only one type of atom) has never been produced. Engin eers would not be particularly in terested in such a metal even if it were to be produced, because it would be soft and weak. The metals used commercially in evitably con ta in small amounts of one or more foreig neleme nts, either metallic or nonmetallic. These foreig neleme nts may be detrimental , they may be 它们的重量占所有生产出来的金属重量的98%在结构应用（也就是说，可以承受载荷的结构）中居于其次位置的是铝、铜、镍和钛。
U 1The use of metals has always a key factor in the development of the social systems of man. Of the roughly ['rʌfl ɪ] 100 basic elements of which all matter is composed, about half are classified as metals.金属的开发利用在人类社会系统的发展中扮演了了重要的角色，世界的物质大概由100种基本元素构成，其中一半是金属元素。
The distinction[dɪ'stɪŋkʃən] between a metal and a nonmetal is not always clear cut. The most basic definition centers around the type of bonding existing between the atoms of the element, and around the characteristics [,kærəkt ə'ristiks] of certain of the electrons[ɪ'lɛk,trɑn] associated with these atoms.金属与非金属的区分不是十分的清晰，最重要（基本）的在于元素原子之间的连接形式以及和原子相关联的电子的确定特性。
in a more practical['præktikəl] way, however, a metal can be defined as an element which has a particular package of properties.然而，在更多的实践当中，金属定义为具有一种整体特性的元素。
Unit 1 Metals金属Unit 2 Selection of Construction Materials工程材料的选择淬透性：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，它表示钢接受淬火的能力。
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内部因素，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及晶粒度，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及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。
