优异烧结硬化材料(Ancorsteel737SH)的研发

A auperior sinter-hardenable material

烧结硬化技术能够帮助粉末冶金零件制造商改善生产效率和降低生产成本。但是,新型高性能烧结硬化材料和设备的缺少,已成为烧结硬化工艺发展的障碍。对材料的研究的重点是提高硬化性能和改善压缩性。最近一种具有高的烧结硬化性和高压缩性的新型烧结硬化材料已被研发出来,其性能超越之前的FLC-4608.这项改进可以让制造商在正常的烧结条件和压制条件下获得高的密度和高的性能。本文全面介绍了该材料的基粉在添加不同成分下,常规压制密度所对应的机械性能,同时也介绍了在生产过程中通过添加其它添加剂来获得高密度和高性能的方法。

Sinter-hardening technology has been assisting the P / M parts fabricator by improving processing efficiencies and reducing costs. Furthermore,the barriers to attaining good sinter-hardenability and part performance have been reduced through improvements in materials and equipment developments. Recent material advances have focused on new alloys with increased hardenability and compressibility.A new sinter-hardenable alloy has been introduced which provides improvements in hardenability and compressibility over the well-established FLC-4608 composition. These improvements will allow fabricators to reach higher densities and mechanical performance under typical compaction and sintering conditions. Mechanical performance and materialcapabilities are investigated as a function of density and admixed composition. Additional processing to achieve higher green densities and mechanical performance will also be reviewed.
