Effect of Al addition on intergranular embrittlement behavior of GH3535 alloy induced by fission product Te
Source abstract
Abstract
The effect of Al addition on Te diffusion behavior of a Ni-16Mo-7Cr base superalloy was investigated at 800 °C for 100 h. The results show that Ni 3Te 2 and Cr 3Te 4 are the mainly reaction products formed on the surface of Al-modified alloy. Although no aluminum telluride is detected both on the surface and in the alloy, the addition of Al promotes the formation of compact and continuous Cr 3Te 4 layer on the surface, which effectively inhibits the diffusion of Te into the alloy. Moreover, Al can also promote the γ` phase formation, and thus improve the tensile property of the alloy significantly.
