Hardness Analyses and Strain Calculation of Spinning Top Roller

细纱胶辊的硬度分析和应变计算

In the process of deep-drawn strain test for CR 304 stainless steel plates, the strain distribution law in each area of the deep-drawn parts, the martensitic transformation analysis, wall thickness and history of hardness change are carefully studied through using martensitic transformation analysis method.

应用马氏体转变分析方法，对304不锈钢冷轧板拉深应变试验过程中拉深件各个区域的应变分布规律、马氏体转变分析、壁厚、硬度变化历史进行了研究；

The influences of the kind, the volume fraction and the relative hardness of the second phase and of plastic strain ε in steel as well as of initial surface roughness R_0 on the surface roughening behaviour in free forming are investigated.

研究了塑性变形量ε、钢中第二相的种类、数量和相对硬度比及初始表面粗糙度R0对自由成型表面粗糙化行为的影响。
