文摘

The dendritic microstructure of the Inconel 625 clads was modified as a result of the high-temperatures exposition in air. The exposition to high temperature produced the formation of carbides and secondary phases in the interdendritic zones. The clads treated at high temperature showed higher values of elastic modulus and hardness than those as-deposited. Higher values of elastic modulus and hardness were measured after the heat treatment at 520°C than to 800°C. The elastic modulus of the secondary phases and carbides generated at high temperature were estimated.
