Investigation of the Elastic Behavior of Al-Li-X Alloys.

Abstract

The goal of this research is to identify and understand critical parameters governing the elastic moduli of commercially important Al-Li-X alloys (X designates copper, magnesium or both). The basic knowledge gained during the project can be used toward further development aluminum-lithium alloys in terms of optimized stiffness. The Young's modulus, shear modulus and Poisson's ratio are calculated from the density and the propagation rate of longitudinal and transverse 10 MHz ultrasonic waves.
