Experimental measurement an elaborate analysis of strain hardening exponent in tensile deformation

摘要

This paper gives a set of formulae for measuring strain hardening exponent n in different typical deforming routes by using experimental parameters P (forming load), V (velocity of cross- ening exponent at constant strain rate), nv (strain hardening exponent under constant velocity ) and np (strain hardening exponent under constant load) is established when ε, v or p is constant distinctive- ly.
