Properties of Prealloyed Steel Powder Metallurgy Products

Abstract

A program to evaluate the properties of prealloyed steel powders, consolidated by various fabrication techniques, was conducted. Sixteen lots of low-alloy prealloyed steel powder, representing seven different major alloys (4130, 1040, 8620, 4640, 4650, 8650, and 9450) were formed into test specimens, heat treated, and tested. Processes used to fabricate the test specimens included die press and sinter, isostatic press and sinter, not repress (limited deformation forging), and high-energy rate forming (HERF). With all fabrication procedures employed, commercial practice was closely adhered to; no attempt was made to optimize any given fabrication procedure. Tensile and impact property data, and the dependence of these values on fabrication and heat treatment parameters are presented.
