Aspects of the physical metallurgy of creating composite articles made of high-temperature nickel alloys

One of the advantages of granule metallurgy is the possibility of forming composite articles consisting of different alloys. As elements connected with articles made of granular alloys it is possible to use both granular components and elements prepared by another technology (cast, wrought). Preparation of combined blanks makes it possible solve a number of problems of modern engine building, including preparation of the critical parts of gas turbine engines (compressor and turbine disks, rotor wheels with fixed blades, etc.), whose properties correspond most completely to the temperature and force conditions for operation, and also blanks with inserts which exhibit better production properties cutability, weldability, etc. 2 refs., 5 figs.
