Engineering Method for Analysis of the Ability to Strain-Hardening of Steels

Abstract

The strain-hardening ability has been estimated using a methodologically simple engineering criterion. A simple engineering method estimates the ability of metals and alloys to strain-hardening by the hardness increase determining. The Rockwell hardness has been measured at the bottom of the indentation cup of the Brinell press indenter. The strain-hardening tendency is investigated by the “two hardness-measuring instruments” method for two austenitic manganese steels, 110G13L and 110G6L, with different austenite stability to strain martensitic transformation. This hardness estimating method can be applied without making special samples and using deforming equipment.
