The high alloy content of advanced nickel-base disk superalloys calls for powder metallurgy (P/M) processing to minimize segregation produced by conventional cast & wrought processing. Although the technology has developed to allow reliable application of P/M materials, of concern are ceramic inclusions which are intrinsic to the process due to the use of ceramic crucibles in producing the raw meltstock and in the powder atomization process itself.
