利用双剪切蠕变试样在受剪切区的筏化试验结果和不同晶体取向试样的蠕变持久寿命试验结果,对镍基单晶合金的蠕变筏化预测模型和蠕变持久寿命模型进行考核,证实此2个模型的合理性。
The creep raft prediction model and creep life expectancy of nickel-based single crystal alloys were investigated by using the results of the raft test in shear zone and the creep life-span test of different crystal orientation samples. Model assessment to confirm the rationality of these two models.
