Resumo
Al-Mg based alloys have special attention due to the lightness of the material and certain mechanical properties and reciclability. Normally classified as non-heat-treatable these alloys obtain higher strength either by strain-hardening or by solid solution. The P/M process in the Al-Mg-Zr alloys in study leading to fine grain structure after the thermal treatment. The understanding of the observed phenomena depends of the fact that materials produced by powder metallurgy present complex interface reactions in a great amount of nucleation sites and a subtle change in the structure of the material causes an important variation in your properties. Alloys in study presented interesting values of properties, with evident technological potential.
