Significance of Charpy-V Test Parameters as Criteria for Quenched and Tempered Steels

Abstract

A ductility parameter has been suggested to replace the energy parameter as the criterion of performance of a quenched and tempered steel. The lateral expansion (LE) of the Charpy v specimen has been hypothesized to be a self-adjusting index of fracture resistance to compensate for the wide range in the yield strength of quenched and tempered steels. This hypothesis is examined using information from an extensive bank of data generated at NRL as well as the information in the literature.
