ESTIMATION OF YOUNG’S MODULUS, SHEAR MODULUS AND ELASTICITY LIMIT OF Al-Cu AND Al–Cu-Zn SYSTEMS USING THE MICROHARDNESS AND MECHANICAL SPECTROSCOPY METHODS

Abstract

The paper estimates normal elasticity modulus E (Young’s modulus), shear modulus G and  proportionality (elasticity) limit σ_pr for aluminum alloys Al-2%Cu, Al-4%Cu, Al-4%Cu-1%Zn and Al-4%Cu-6%Zn using the microhardness and mechanical spectroscopy methods, which enables their wide application for obtaining standard as well as special mechanical characteristics of  materials.
