Experimental Study and Mathematical Modeling of Development of Crystallographic Slip in Heterophase FCC Alloys

Article Preview

Abstract:

The experimental results of plastic behavior investigation of Al-6%Zn-3%Mg alloy are compared with the mathematical model of plastic deformation of dispersion hardened FCC materials with undeformed particles. Were determined the factors, when model properly describes the regularities of slip development in this alloy.
