PRESENT SITUATION AND LATENT POTENTIALITIES OF P/M SUPERALLOUS

The current development and how continuing explaoittion potentialities of P/M superalloys have been recounted in this paper. Especially a suggestion and measures are made in selecting manufacturing process and controlling to assume high quality powder products. The ontrolling factors of low cycles fatigue in P/M quperalloys have also been detailed investigated. Improving low cycles fatigue is the koy to the continuing exploitation potentialities of P/M superalloys.
