基于最大降低相界面能密度原理，本文推导了一般应力状态下镍基单晶合金的强化相γ＇筏化准则，给出了筏化图，并得到试验结果的验证，进而定量分析了核化过程；利用该准则即最大相界面能密度降低，可以很好地描述蠕变性能的晶体取向相关性，并初步得到试验结果的验证．
Based on the principle of maximum densifiable interface energy density, this paper derives the γ ’rafting rule of the strengthened phase of nickel-based single crystal alloys under normal stress conditions. The raft map is given and verified by the test results. The nucleation This criterion can be used to describe the dependence of the crystal orientation on the creep properties and to verify the experimental results.
