摘要
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。
The desire for advanced ferrous PM materials has led to the development of alloys that more closely simulate wrought steel compositions.Traditional wrought steel alloying elements,such as Cr,are used to improve mechanical properties,hardenability and are cost effective.Chromium has historically been avoided in PM due to oxygen related issues,but newer PM alloy systems now contain this element.While providing good mechanical properties and overall product cost,proper sintering of these alloys is the critical challenge.This paper presents the role of sintering and composition on the mechanical properties and microstructure of a chromium containing PM steel.
