摘要
通过倒摆内耗仪研究了Al-Zr合金的高温晶界峰和竹节峰的产生和相互关系、竹节峰及其高温背底随退火条件变化的规律和热处理制度对竹节峰的影响。提出了在高纯铝的竹节晶界上可能存在偏析粒子的观点,从而用Mori理论解释了实验中所观察到的实验结果。
The paper studied the emergenoe and relation of high temperature friction grain boundary peak and bamboo peak. The change of the bamboo peak and its high temperature background with the variation of the annealing condition as well as the affect of the bamboo peak by heat treated condition in an Al-Zr a lloy are investigated by using a low frequency inverted torsion pendulum, It is proposed that there may be segregation particles on the bamboo grain boundary in high purity aluminum,and explained with Mori's theory.
