The Computer Simulation of Rolling Texture
-
摘要: 分析了金屬軋制變形的模擬過程,提出了新的形變模型(PC模型)。PC模型修正了多晶體內各晶粒變形時的切變邊界條件,允許各種切變在變形過程中部分存在,從而使模擬更接近實際晶體變形過程。與多晶鋁軋制織構的比較表明,PC模型能更好地表達軋制過程中面心立方金屬各晶粒取向,在取向空間內的流動傾向及最終穩定位置。Abstract: The simulation process of rolling deformation in matels is analysed, and a new deformation model (PC-model) is suggested. The new model modifies the shear condition of deformation grains in polycrystal, in which the shears are partially free, so that the simulation could further approach the real cases. According to comparison with rolling texture in Al polycrystal the PC-model could show more accurately the flow tendency of grain orientations in f.c.c matels and their final stable positions in orientation space.
