Analysis of the heat treatment process in the manufacture of metal parts to improve the level of role [Paper Keywords] the manufacture of metal parts heat treatment process to improve [Abstract] This paper discusses three aspects of heat treatment process in the manufacture of metal parts to improve the level of the role. Introduction In modern industrial production, the manufacture of metal parts is an important part, has a pivotal role, thereby increasing the level of manufacturing of metal parts to become an indispensable work in the metal parts of the manufacturing process, heat treatment is to improve important measure of its manufacturing standards in design, the right to develop heat treatment process can change the mechanical properties of some metals, while the unreasonable heat treatment conditions, not only does not improve the mechanical properties of materials, but also disrupts the performance of the original material Therefore, designers should be based metal component, an accurate analysis of metallic materials and heat treatment process and to formulate a reasonable heat treatment process, reasonable arrangement process, to get the desired results, increase the level of the metal parts manufacturing. In modern industrial production, widespread use of metal iron, aluminum, copper, lead, zinc, nickel, chromium, manganese, etc., but used more of their alloys. The internal structure of metals and alloys consists of two aspects: One is the binding mode between the metal atoms, the second is the arrangement of atoms in space.’s performance and the metal atoms are arranged in the configuration space is closely related to the atomic arrangement of different metals on the performance of a difference. To get better performance of the metal to meet the manufacturing and use requirements, we will place a certain piece of metal heated to a suitable medium temperature, and maintained at this temperature in a certain time, on different spee
