工件热处理变形的一种主要形式是形状改变(另种是体积改变),主要是由于工件在被加热、冷却过程中,各部位温度的差别形成的热应力和相变时间有先有后形成的组织应力所造成的。这两种应力会引
One of the main forms of deformation of the workpiece heat treatment is the shape change (the other is the volume change), mainly due to the workpiece in the heating and cooling process, the temperature difference between the various parts of the formation of thermal stress and phase transition time after the first Organizational stress caused by. These two stresses will lead
