Abstract


The changes in the elastic constants at 298 K of polycrystalline samples of pure aluminium (99.5 %) with different levels of cold-working have been determined. The deformation process has been carried out in a tension machine. The properties measured are: Young modulus, E, Poisson ratio, v, and yield strength, σ0,2. The Young modulus diminishes from 70 to 63 GPa for 0-2.5 % deformation (elongation) and then increases with the successive cold-working passes. The Poisson ratio shows a similar behavior whereas the yield strength increases with cold-work. Pure aluminium behavior is similar to that obtained for pure iron (Armco) and for F-1140 annealed steel.
