矿化剂对型壳莫来石及岩相组织的影响

Effect of Mineralizer on Mullite Formation and Lithofacies Microstructure in Mould- shell

研究了五种不同成分的矿化剂及不同焙烧温度对型壳的莫来石形成的影响 ,同时研究了矿化剂成分在三种焙烧温度下对型壳岩相组织的影响。

In this paper,the effect of five types of mineralizer and various sintering tem- perature on the extent of forming mullite in a mould- shell for single crystel superalloy blades has been studied,also the effect of mineralizer composition on the lithofacies microstrucfure at three sintering temperature has been reseached.
