PRESENT SITUATION AND LATENT POTENTIALITIES OF P/M SUPERALLOUS

摘要: 本文论述了粉末高温合金的现状。对用不同工艺路线生产的粉末高温合金的性能进行了对比。提出了进一步严格控制生产工艺,提高性能,保证产品质量的措施和今后粉末高温合金的研究方向。

Abstract: 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.
