Development and Application of P/M Superalloy

P/M superalloy becomes excellent material for fabricating turbine discs used for advanced aviation enging due to its special structure and properties.To advance the applicable property and security of aviation enging,the material from melting original alloy to engineering application of turbine disc was studied,and remarkable results in aspect of so many key technologies were gained due to the result of the foundation of fabricating technique for turbine disc and the establishment of process and testing documents.Numerical simulation is widely used to fabricate P/M turbine disc for the purpose of shortening studying period and optimizing processes,and the preparatory experimental results were achieved.
