摘要
测量了夹角分别为60°和153.4°的[110]对称倾侧铝双晶晶界的扭转滞弹性蠕变曲线,指出了晶界的弛豫强度在低于温度T_0时变为零,此温度(T_0)约等于该金属的熔点温度(T_m)的二分之一,这说明晶界的内部结构在这个温度的附近发生了显著的变化。
Anelastic creep curves of [110] symme rical tilt boundaries with mis-orientation angles 60°and 153.4°in aluminium bicrystals has been measured in torsion. It was found that the relaxation strength associated with the boundary becomes zero below a temperature To which has a value of about one half of the melting temperature Tm of bulk aluminium. This shows that a perceptible change of the internal structure of the grain boundary has taken place around this temperature.
