Alloying elements alter the Ms temperature significantly, but do not alter the characteristic that transformation is largely independent of cooling rate. In maraging steels, fully martensitic structures are formed even during very slow cooling of heavy sections from the solution-annealing temperature.

Silverchair Information Systems, Charlottesville, Va., announces a partnership with ASM International, Cleveland, to develop a unified hosting solution for ASM’s authoritative materials information resources.
Continue readingOne Minute Mentor: Austenite Reversion on Heating
Age hardening of martensite, or maraging, depends on the occurrence of a thermal hysteresis of phase transformations, whereby the reversion of martensite to austenite during reheating occurs at a higher temperature range than the temperature range for martensite formation during cooling.
