热处理工艺是机械制造过程中的重要工序,在西方国家航空工业中与表面处理、焊接、胶接、无损探伤等同属特种工艺。由于热处理关系到零件的内部质量、零件的使用寿命、产品的可靠性,以及最大限度发挥材料的潜力等一系列重大问题,因此有着特殊的意义。近年来,部分工厂在同国外协作、加工订货等交往中,得到了西方几个国家的公司的一些工艺资料。其中有不少是热处理工艺及其质量控制方面的,在一定程度上反映了国外航空 Heat treatment process is an important process in the mechanical manufacturing process, in the Western countries with the surface treatment of aviation industry, welding, gluing, non-destructive testing belong to the same special process. This is of special significance as the heat treatment concerns a number of major issues, such as the internal quality of the part, the useful life of the part, the reliability of the product, and the potential of the material to its fullest extent. In recent years, some factories in the collaboration with foreign countries, processing and ordering and other contacts, the Western countries received some of the company’s process information. Many of them are heat treatment process and its quality control, to some extent reflect the foreign aviation
