Cobalt-based superalloy
Overview of characteristics and application fields:
This alloy is a cobalt-based alloy reinforced with r and solid solution High-temperature alloys have moderate durability and creep strength below ℃
, excellent oxidation resistance below ℃
, and satisfactory process properties such as forming welding. It is suitable for manufacturing hot-end high-temperature parts that require medium strength and excellent high-temperature oxidation resistance, such as aero-engine combustion chambers and guide vanes. It can also be used on aerospace engines and space shuttles. Mainly used on imported models to manufacture high-temperature parts such as guide plates, turbine outer ring outer wall vortexer sealing plates, etc.

Metallographic structure:
After aging, the alloy can produce some carbides and intermetallic compounds, including
and.
Process performance and requirements:
The alloy has satisfactory hot and cold forming properties. The hot working temperature range is ~
℃
. The forging temperature should be high enough to reduce grain boundary carbides. , should also be low enough to control the grain size, and the suitable forging temperature is about ℃
.
The average grain size of the alloy is closely related to the degree of deformation of the forging and the final forging temperature.
Alloys can be connected by methods such as solution welding, resistance welding and fiber welding.
Alloy solution treatment: forgings and forged bars
℃
, water cooling.
