Résumé : The effect of Mg addns. on the mech. properties of dispersion hardening alloys, prepd. from the eutectic Al-5.7% Ni by casting and isostatic extrusion was detd.. A small amt. of Mg increases significantly the tensile strength and fracture elongation, and esp. stabilizes the alloy structure for annealing at high temp
