THE EFFECTS OF AUSTENITIZING AND TEMPERING ON THE MECHANICAL PROPERTIES OF FULLY QUENCHED HY-80 STEELS

Abstract

The effects of austenitizing, tempering temperatures times on fully quenched low- and high-chemistry HY-80 steels were investigated. Correlation procedures were established for relating notch-brittleness properties to tensile strength for a given Charpy V-notch fibrous fracture appearance. The results indicate that Charpy V-notch transition temperatures increase with increasing austenitizing and decreasing tempering temperatures. For fully quenched HY-80 steels, the optimum Charpy V-notch impact fibrous transition temperatures are attained for the 100,000psi-yield-strength level.
