THERMOMECHANICAL TREATMENTS OF THE 18% NI MARAGING STEELS,
Abstract
Thermomechanical treatments applied to the maraging steels include (a) cold working in the austenitic condition at 650F, followed by transformation to martensite and aging, (b) cold working in the martensitic condition and aging, and (c) cold working in the aged condition with and without subsequent re-aging. The strength increases in these steels are very small compared to the increases observed in conventional carbon and alloy steels. The changes that are observed are compatible with the strengthening mechanisms operative during thermomechanical treatment of conventional steels, however. Differences are caused by the absence of a carbide precipitate and the low work-hardening rate in both the solution-treated and the aged conditions. (Author)
