AB-Ⅰshowed single and symmetrical peak, a light yellow powder was obtained after dialyzation and freeze-drying. AB-Ⅱand AB-Ⅲwere devided into two parts, collected the main peak, we gained AB-Ⅱ-b which was yellow powder and AB-Ⅲ-b which was brown powder.

AB-Ⅰ、AB-Ⅱ和AB-Ⅲ分别再通过Sepharose CL-4B凝胶层析进一步分级,AB-Ⅰ得到单一对称峰,透析干燥后为淡黄色粉末,AB-Ⅱ和AB-Ⅲ在主峰之前分别有一小峰,收集主峰,得到AB-Ⅱ-b和AB-Ⅲ-b,透析干燥后分别呈黄色和褐色粉末

The milled powders with either ethanol or stearic acid as PCA remain a solid solution structure eyen after 12h milling, but both transform to FeAl (B2) intermetallic after subsequent vacuum annealing at 1100℃, during which more Al2O3 is formed in the ethanol milled powders.

两种粉末经12h球磨后,仍保持固溶体结构;经1100℃真空热处理后,两者均可转变为FeAl(B2)金属间化合物,但无水乙醇作PCA的球磨粉末中Al2O3生成量相对较多。

It is very detrimental to materials performance. From the viewpoint of the effects of PPB precipitation on the frature of hipped P/M Rene'95, the surface segregation and reaction in Rene'95 powder metallurgy superalloy were analyzed by modern surface techniques and by electron microscopy. The mechanisms of the formation and reduction of PPB precipitation are revealed.
