对先进铁基粉末冶金材料的期望,已导致开发了更接近模拟锻钢组成的合金。像Cr等传统锻钢合金化元素,已用于提高力学性能与淬透性,而且成本可行。过去在粉末冶金中避免用铬是因为与氧相关的问题,但现在较新的合金系都含有这种元素。尽管这些合金可提供良好的力学性能与生产总成本可行,但这些合金的适当烧结仍是关键性问题。将介绍烧结条件与组成对含Cr粉末冶金钢的力学性能与显微结构的影响。 Expectations for advanced iron-based powder metallurgy materials have led to the development of alloys that are closer to simulated forged steel compositions. Traditional as forged alloys such as Cr alloying elements have been used to improve the mechanical properties and hardenability, and the cost is feasible. In the past, chromium avoided in powder metallurgy because of oxygen-related problems, but newer alloys now contain this element. Although these alloys provide good mechanical properties and overall production costs, the proper sintering of these alloys is still a critical issue. The effects of sintering conditions and composition on the mechanical properties and microstructure of Cr-containing powder metallurgy steel will be introduced.
