两种氩气雾化粉末颗粒热处理后的组织变化

Microstructures of Argon-Atomized FGH95 and Imported Rene'95 Superalloy Powders after Heat Treatment

    摘要
  • 摘要: 本文着重研究FGH95和Rene'95两种粉末经热处理后组织的变化。实验结果指出:树枝晶蛆织较胞状晶组织难于均匀化。在1140℃加热3h后粉末的铸态组织才能完全消除达到均匀化。FGH95粉末中γ'相溶解温度较Rene'95粉末中的低。

     

    Abstract: Microstructures of argon-atomized FGH95 and imported Rene'95 superalloy powders after heat treatment were studied.It is shown that homogenization of dendritic microstructure is more difficult to complete than that of cellular mie-rostructure. The dendritic microstructure can be homogenized during heat treatment at 1140℃ for 3h. The solution temperature of FGH95 powder is lower than that of Rene'95.
