本文讨论了工具钢抵抗不同失效机制的关键性能，以及常规制造的工具钢和粉末冶金生产的材料之间的性能。将证明这两种新型高性能粉末冶金（P/M）工具钢具有许多独特的特性，与用于金属成形应用的其他更标准的工具钢相比，这将提高工具性能。

THIS PAPER DISCUSSES PROPERTIES THAT ARE CRITICAL IN A TOOL STEEL FOR RESISTANCE TO THE DIFFERENT FAILURE MECHANISMS AND IN PERFORMANCE BETWEEN CONVENTIONALLY MANUFACTURED TOOL STEEL AND POWDER METALLURGICAL PRODUCED MATERIALS. IT WILL BE DEMONSTRATED THAT THE TWO NEW HIGH-PERFORMANCE POWDER METALLURGICAL (P/M) TOOL STEELS POSSESS A NUMBER OF UNIQUE CHARACTERISTICS WHICH WILL RESULT IN ENHANCED TOOLING PERFORMANCE OVER OTHER, MORE STANDARD, TOOL STEELS USED FOR METAL FORMING APPLICATIONS.
