Abstract
The amounts of retained austenite in the powder high-speed steel GPM A30 were calculated using a Rietveld computer model, and the relationship between the microstructure and hardness was studied. A test of the mechanical properties yielded the best heat treatment conditions and supported the production of high-quality A30 high-speed steel. The goal of this work was to estimate the amount of austenite retained following various heat treatments, and the mechanical properties of A30 P/M high-speed steel were further studied. © ASM International 2007.
