Mechanical Property Development in Hot Isostatic Pressed (HIP) Low Alloy Steel Powder.

Abstract

The mechanical properties of a low alloy steel gas atomized powder, which was hot isostatically pressed (Hipped) to full density, were developed using typical commercial heat treatment practices. Tempering temperatures were varied systematically from 1000 F to 1200 F and the tensile and impact properties evaluated along with the corresponding microstructural conditions. Yield strengths on the order of 180,000 psi accompanied by low temperature, impact toughness values of 18-20 ft-lb were developed in billets of this material, 4 inches in diameter. The results of this study demonstrate that hot isostatic pressing of low alloy steel powder can be utilized to produce high quality components for critical applications which will benefit from near-net shape manufacturing techniques.
