Paper Abstract

The supersaturated solid solutions of Cr and Ni were formed in (alpha) -Al during laser treatment. Chromium solid solution was formed as a result of doublepass laser treatment of pure aluminum electroplated with chromium. It is reported that Cr distribution along the depth of the melted zone is not uniformal. The concentration of chromium is maximum at the alloy's surface, reducing to zero as depth increases. This data is related to microhardness tests. Ni solid solution was formed as a result of doublepass laser treatment of Al-5% Ni alloy. The distribution of nickel in solid solution is uniformal, but SEM study of the microstructure revealed that solid solution is only formed close to the melted pool bottom.
