Effect of yttrium on intergranular embrittlement behavior of GH3535 alloy induced by tellurium
Source abstract
Abstract
The influence of yttrium (Y) addition on the tellurium (Te) induced intergranular embrittlement of Ni-16Mo-7Cr alloy was investigated. The results show that the addition of Y remarkedly reduces the diffusion depth of Te into the alloy, and thus improves the intergranular cracking resistance of the alloy. The YTe phases on the surface reaction layer and near-surface grain boundaries, plays an important role in fixing Te and slowing down the Te diffusion. Adding more than 0.05 wt% Y into the alloy does not continuously improve the intergranular embrittlement resistance, and even damages the mechanical properties.
