Abstract : The relation hip between the strain o which rocket motor cases r subjected during proof te ting to subsequent premature failure was investigated. Two aspects of the role of strain on the mechanic l propertie w re co id r Thefir t i th effect of strain on the retained austenite and the second is the effect of strainAND SUBSEQUENT RETEMPERING ON THE TEMPERED MARTENSITE. In ddition to the mechanical property investigation, retained austenite determinations and lectron microscopic observations were carried out on specimenin seteddions of heat-treatment (Author
