一、热处理时工件为什么会变形? 工件以不同方式进行热处理时,钢件变形会因冷却速度与转变产物不同而有差异。因为在热处理时钢内要发生组织转变(不同组织比容不同),工件断面各处冷却速度及组织转变情况又会因种种原因而有差异,所以工件各处会产生不均一的组织应力和热应力;应力平衡的结果将在工件各处引起大小不同的弹性和塑
First, the heat treatment when the workpiece deformation Why? When the workpiece is heat treated in different ways, the deformation of the steel due to the cooling rate and the different products are different. Because in the heat treatment to occur when the steel within the organization (different tissue specific volume of different), parts of the cooling rate throughout the section and the organizational change will vary for a variety of reasons, so the workpiece will have uneven throughout the organization stress and heat Stress; the result of stress balance will cause different sizes of elasticity and plastic throughout the workpiece
