在300 ~ 1273 K温度范围内对Ti 3 Al单晶进行了沿着c轴压缩。屈服应力表现出异常的温度依赖性，峰值在1120 K左右。通过双面迹线分析确定滑移面为{1121}，观察到的位错具有Burgers矢赝，为1126 μ m，且多为刃型位错。一个可能的机制异常进行了简要的讨论。
Abstract Ti3Al single crystals have been compressed along the c axis at temperatures from 300 to 1273 K. The yield stress shows an anomalous temperature dependence with a peak at around 1120 K. Slip planes are determined to be {1121} by two-surface trace analysis and dislocations observed have Burgers vector ⅓,〈1 126〉 and are mostly of edge character. A possible mechanism for the anomaly is briefly discussed.
