研究了δ相对ＧＨ４１６９合金持久性能的影响。结果表明，δ相数量过多或过少都会对合金持久寿命产生不利影响，当δ相数量约为４．８２％时，合金持久寿命达到最大值。
The effect of δ on the ductility of GH4169 alloy was studied. The results indicate that too much or too few δ phases will adversely affect the life expectancy of the alloy. When the δ phase number is about 4.82%, the alloy reaches the maximum value.
