In order to examine mechanical properties and recovery rate during deformation of Al-Fe, Al-Go and Al-Ni alloys, and to compare them with those of pure aluminum, room temperature tensile tests have been carried out.
These materials have high tensile ductility and exhibit steady state deformation at high strains. In this deformation range characteristic dislocation cell structures were observed on transmission electron microscopic examination, and the contribution of internal stress to applied stress was nearly 100%, so that deformation of these alloys are understood by the recovery controlled mechanism. Recovery rate depended strongly on strain rate, while no apparent difference in recovery rate was observed between the materials at a constant strain rate.
