钢铁是机械工业中应用广泛的材料,通过热处理工艺,可以获得不同的机械性能。正确的热处理工艺可以提高金属材料的机械性能,不合理的热处理工艺会破坏材料原有的组织,降低机械性能。因此,制订合理的热处理工艺,合理安排工艺流程,才能提高金属零件的机械性能。 Steel is a widely used material in the machinery industry, and different mechanical properties can be obtained through heat treatment processes. The correct heat treatment process can improve the mechanical properties of metal materials, unreasonable heat treatment process will destroy the original material structure, reduce mechanical properties. Therefore, the development of a reasonable heat treatment process, a reasonable arrangement of the process, in order to improve the mechanical properties of metal parts.
