  In these kinds of Ni-based alloys,big brittle macroscopic inclusions have the huge impact on the properties of alloys,especially the composite inclusions composed of Ti、Al、Fe in 4J43 alloy and Cr20Ni80 alloy. This kind of impurity is mainly titanic oxides or nitrides generated by oxidizing of titanium in smelting which exhibits abnormal acute angle with size of 20-300μm and higher rigidity,belonging to brittle impurity with low strain rate.

  其中,大尺寸的脆性宏观夹杂物对合金的性能影响最大,尤其是4J43和Cr20Ni80合金中由Ti、Al、Fe组成的复合夹杂物,这类夹杂物主要是熔炼中钛脱氧产生的钛的氧化物或氮化物,多以锐角规则形貌出现,尺寸在20-300μm,变形率低、并具有较高的硬度。
