一、引言近年来,由于合金设计和合金相分离,需要计算合金中γ＇相的数量。Woodyatt,Sims等利用对合金各相逐次递减的方法,得到合金中γ＇相的数量。Decker应用回归分析方法,由某些工业合金的实验资料,得出一个以体积百分数表达的计算公式. 作者对目前已经发表的沉淀强化镍基合金γ＇相的大量实验资料,进行综合分析,归纳成以下三条: 1.合金中所含碳化物相数量较少(总量在3％以下),其它相(如硼化物等)含量甚微,二者总和比γ＇相的数量少得多,可予以忽略不计,因而这种合金可以视为由γ奥
I. Introduction In recent years, due to the alloy design and alloy phase separation, the amount of γ ’phase in the alloy needs to be calculated. Woodyatt, Sims and other use of the alloy phase by decreasing the number of ways to get the number of γ ’phase alloy. Decker applied regression analysis method to obtain a calculation formula expressed in terms of volume percent from the experimental data of some industrial alloys.The author made a comprehensive analysis of a large amount of experimental data of the γ ’phase of the precipitation strengthened nickel base alloy that has been published so far Into the following three: 1. The alloy contains a small amount of carbide phase (the total amount of less than 3%), other phases (such as borides, etc.) content is very small, the total sum of both less than the number of γ ’ Can be neglected, so this alloy can be regarded as by γ Austria
