Relative work hardening rates

Abstract

Until recently some authors of papers and textbooks have given the erroneous impression that increased work hardening rate always leads to increased maximum uniform strain. Recently, it has been recognized that such a statement is true only if the tensile strength remains constant. Marder used the expression TS × e _u, where TS is the tensile strength and e _u is the maximum uniform strain, to characterize the performance of a steel.
