Workability of 1045 spheroidized steel under superimposed hydrostatic pressure

View publication

Abstract

Workability tests were performed on spheroidized {dy1045} steel to investigate the variation of forming limits due to the suppression of void growth under superimposed hydrostatic pressure. Results showed that increasing pressure enhances formability, as expressed by the increasing intercept and decreasing slope of the forming-limit line. A continuum mechanical model based on the growth and coalescence of voids under externally applied pressure is proposed that ex-plains the experimental results. © 1989 The Metallurgical Society of AIME.
