TENSILE AND ELASTIC PROPERTIES OF DEFORMED BINARY ALUMINUM-ALLOYS WITH 10-20 VOL-PERCENT OF 2ND-PHASE

The tensile and elastic properties of deformed binary aluminum alloys belonging to Al-Ni, Al-Fe and Al-Cu systems with 10 to 20 vol.% of sec ond phase are studied. After deformation according to the technology p roposed and recrystallization annealing, the sheet and rod metal had t he normal elasticity modulus increased by 15-25% and mechanical proper ties comparable to those of medium-strength wrought aluminum alloys. A linear dependence of the tensile strength, relative elongation and el asticity modulus on the volume fraction of the second was established. The dependence of the normal elasticity modulus can be described by t he equal phase and matrix deformation model. The application of hetero geneous alloys of eutectic systems as deformable materials is consider ed as promising.
