摘要
烧结-硬化工艺,因为不需要再进行热处理,已发展成制造淬硬粉末冶金零件非常有效的一种减低成本的生产方法。最近几年,在烧结-硬化材料系统和烧结炉技术方面都取得了进展。这篇论文将评述这些进展和制造优质烧结-硬化零件所需要的一些关键工艺参数。涉及的具体内容有:合金选择,力学与疲劳性能,显微组织改进,烧结炉冷却速率最佳化及正确的回火周期。
Sinter-hardening has developed into a highly cost effective production method for the production of through hardened P/M parts without the need for additional heat-treatments. Over the last several years advances have been made in sinter-hardening material systems and furnace technology. This paper reviews these advances as well as some key processing parameters required to produce high quality sinter-hardened components. Specific topics included are proper alloy selection ,mechanical and fatigue properties ,microstructural development ,optimization of furnace cooling rates, and proper tempering practices.
