Heat Treatment Process Of Cobalt Base Alloy
Sep 03, 2017

The size and distribution of the carbide particles in cobalt base alloy and the grain size are very sensitive to the casting process, and the casting process parameters must be controlled to achieve the required durability and thermal fatigue properties of the cast cobalt base alloy components. The cobalt base alloy should be treated with heat treatment, mainly controlling the precipitation of carbide.

For the casting of cobalt base alloy, first of all, high temperature solution treatment, the temperature is usually 1150 ℃, so that all the primary carbide, including some of the MC-type carbide into solid solution, and then in 870-980 ℃ aging treatment, so that the carbide (the most common precipitation) again.
