冷轧钢板变形织构的理论模拟

采用取向分布函数法研究了钢板中的轧制织构。其中以｛１１０｝＜１１１＞滑移系滑移为基本变形机制，利用Ｓａｃｈｓ，Ｔａｙｌｏｒ，ＲＣ和ＰＣ等模型对轧制织构进了理论模拟。这些理论模型可以再现体心立方金属冷轧过程中晶粒取向在｛１１２｝＜１１０＞，｛１１１｝＜１１０＞，｛１１１｝＜１１２＞及｛００１｝＜１１０＞附近的聚集过程。分析表明｛１１０｝＜１１１＞滑移系的滑移是体心立方金属十分重要的变形机制，适当参考

Theoretical Simulation of Rolling Texture Development in Steel Sheets

The ODF method was applied to investigate the rolling texture develop -ment in steel sheet. The texture was also simulated by the Sachs ,Taylor, RC and PC models with {110} < 111 >ip systems. The theoretical models could reproduce the orientation accumulation around {112} < 110>l11] <110>l11}< 112>d {001} < 110>t was shown that the {110} < 111 >ip is very important deformation mechanism in b.c.c. metals. The rolling deformation process can be described more accurately if the assumptions of all models are considered properly. The continuities of both stress and strain during rolling deformation of steel sheet were also discussed.
