材料成型及控制工程科目英文Materials Forming and Control Engineering is a specialized subject that focuses on the various processes involved in shaping and controlling materials to create desired products. It is a multidisciplinary field that combines knowledge from mechanical engineering, materials science, and industrial design.The aim of Materials Forming and Control Engineering is to explore the different methods and techniques utilized in the manufacturing industry to shape materials into specific forms. This includes processes such as casting, molding, extrusion, forging, and sheet metal forming. These processes are crucial in the production of a wide range of products, from automotive parts to kitchen appliances. One aspect of Materials Forming and Control Engineering is the study of material properties and behavior during the forming process. Researchers in this field investigate how materials respond to external forces, such as heat and pressure, and how they deform and change shape. This knowledge is essential in determining the optimal process parameters and ensuring high-quality product outcomes.Another important aspect is the development of control systems for manufacturing processes. Engineers in this field design and implement control algorithms and systems to regulate the various parameters involved in the forming process, such as temperature, pressure, speed, and timing. These control systems aim to ensure consistent and precise shaping of materials, reducing waste and improving productivity.Moreover, Materials Forming and Control Engineering also addresses the challenges related to material defects and quality control. Engineers study the causes of defects, such as cracks, voids, and surface imperfections, and develop strategies to minimize their occurrence. They also design inspection methods and quality control processes to detect and eliminate defective products during manufacturing.The advancements in computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies have significantly contributed to the field of Materials Forming and Control Engineering. These tools enable engineers to simulate and analyze the forming process digitally, optimizing the design and manufacturing parameters before the actual production begins. This helps in reducing costs, improving efficiency, and enhancing product quality.In conclusion, Materials Forming and Control Engineering plays a vital role in the manufacturing industry by exploring and applying various methods and technologies to shape and control materials. It encompasses the study of material behavior, the development of control systems, and the implementation of quality control processes. With continuous advancements in technology, this field is constantly evolving to meet the demands of modern manufacturing and drive innovation.。

•因为温度和压力组合的范围很广,可以从高温无压力到高压无温升,焊接可以在各种条件下完成,多焊接工艺得到了发展,并应用于日常生产中。
•普通人对于焊接作为一种生产工艺的重要性了解很少,但是,如果不使用焊接,金属产品的很大部分都会有很大的改变,这将急剧地提高成本,降低生产效益。
•为了获得两种金属之间的良好结合,所焊接金属的原子必须相近且具有活性,这样才能形成金属晶体。
•理想的冶金结合需要(1)绝对光滑,平整,相匹配的表面;(2)洁净的表面,没有氧化物,吸附气体,油脂或其它杂质;(3)金属内部没有杂质;(4)两种金属是具有相同晶体学取向的同种晶体。
显然,即使在理想的条件下,这些条件都是很难达到的,在实际条件下,要满足这些条件是不可能的。
•因此,设计各种方法来克服实际中的不足,从而达到理想条件。
•各种焊接工艺不仅在温度压力组合与获得(方式)上有很大不同,而且对于焊接前金属表面的清理和焊接过程中可能出现的氧化或污染必须给予的关注程度也不相同。
•如果使用高温,金属的大部分将会受到环境的不利影响,如果实际焊接中,金属融化了,金属将会发生很大的变化。
而且,由于连续的加热和冷却,金属的结构和质量也会受到不利影响,这些影响是我们必须要考虑的。
•总之,为了得到满意的焊接,需要合理的加热和压力源,一种保护金属和清洁金属的方法,防止或弥补不利的冶金作用。
