THE EFFECT OF REVERTED AUSTENITE ON THE MECHANICAL PROPERTIES AND TOUGHNESS OF 12 Ni AND 18 Ni (200) MARAGING STEELS.

Abstract

The effect of reverted austenite, of inclusion density, and of overaging of hardening precipitates, separately and together, on the strength and toughness of some maraging steels was investigated. The presence of reverted austenite does not necessarily improve toughness, and can in fact contribute measurably to increased yield strengths. Some speculations are presented on the role of retained austenite in these steels, and on the influence of the dislocations produced during the original austenite-martensite transformation. (Author)
