Simulation of the flow stress of recrystallized single-phase alloys of the Al-Mg and Al-Cu systems

For single-phase recrystallized alloys of the Al-Mg and Al-Cu systems, a model of the dependence of the flow stress on the concentration of the doping element, grain size, and degree of residual deformation is suggested. A physical approach for analysis of the mechanism of alloy strengthening demons...

Description
Summary:For single-phase recrystallized alloys of the Al-Mg and Al-Cu systems, a model of the dependence of the flow stress on the concentration of the doping element, grain size, and degree of residual deformation is suggested. A physical approach for analysis of the mechanism of alloy strengthening demonstrated a similarity in the dependences of the flow stress in various systems, which permitted developing a universal model for the alloys under consideration. The calculation error is within 6%.[PUBLICATION ABSTRACT]
