Microstructure and Properties of P/M Tool Steels.

Abstract

A detailed microstructural examination has been made of T15 and Tex 25 high speed tool steels processed from rapidly solidified gas atomized powders, and associated strength and toughness evaluated. Powders were screened into selected size fractions, hot isostatically pressed to full density and heat-treated. Two HIPing temperatures, two austenitizing temperatures and three tempering temperatures were included in the study. Atomized and consolidated materials were characterized utilizing x-ray diffraction, optical and scanning electron microscopy. Both cellular and dendritic structures are present in the atomized powders depending on particle size, with MC carbides primarily at cell boundaries.
