钼单晶体的冷轧及再结晶织构

本文研究了(110)001]和(111)112]取向的钼单晶体,在经过70％、80％和85％冷轧后的加工織构,以及退火后的再结晶織构。分析了(111)112]取向晶体在轧制变形时,由于各组滑移系间的交互作用而引起晶体取向的转动,从定向生核的观点,能够比较满意地解释这类取向的晶体随着压下量从70％增加到85％,再结晶織构从(221)114]、(110)001]向着(320)001]和(210)001]逐渐变化的现象。 关键词：

COLD-ROLLED AND RECRYSTALLIZATION TEXTURES OF MOLYBDENUM SINGLE CRYSTALS

The cold-rolled and recrystaliization textures of molybdenum single crystals of (110)001] and (111)112] orientation after a reduction in thickness of 70, 80 and 85 pet were investigated. As the reduction in thickness increased from 70 to 85 pet, the recrystaliization textures gradually changed from the (110)001], (22l)114] orientations towards the (320) 001] and (210) 001] orientations. These results can be satisfactorily explained by the point of view of oriented nucleation.
