INVESTIGATION OF THERMAL EMBRITTLEMENT IN 18NI (250) MARAGING STEEL

Abstract

The ultrahigh-strength 18Ni maraging steels may be severely embrittled by certain high-temperature thermal treatments involved in processing and fabrication. Investigation objectives were to (1) survey the thermal embrittlement characteristics of a commercial 18Ni (250) maraging steel, (2) determine the thermal treatments that result in a maximum degree of embrittlement, (3) discover the metallurgical sources of the embrittlement, and (4) improve the resistance of the steel to thermal embrittlement by alloy modification.
