【摘要】 冷轧形变量为98%的高纯镍在不同温度下进行退火,采用基于扫描电镜(SEM)上的电子背散射衍射(EBSD)分析方法研究它的回复与再结晶行为。结果表明,在220℃的退火条件下,材料开始发生回复,再结晶晶核形成;随着退火温度的升高,退火时间的延长,再结晶的程度加深。在再结晶的过程中立方取向的晶粒占主导地位。更多还原

【Abstract】 High purity nickel rolled to a reduction of 98% was annealed for different temperatures and times.The recovery and recrystallization of the nickel during annealing was investigated by the electron backscatter diffraction technique in the scanning electron microscope.The results show that recovery and nucleation begin at 220℃.With increasing annealing temperatures and/or times,the recrystallization continues to completion.During annealing,the cube-oriented grains grow to dominate the microstructure.更多还原
