Influence of Hydrostatic Extrusion on the Mechanical Properties of the Model Al-Mg Alloys

Abstract Two model aluminium-magnesium alloys, containing 3 and 7.5 wt.% of Mg, were subjected to plastic deformation by means hydrostatic extrusion (HE). degrees imposed two subsequent reductions the diameter. Microstructural analysis tensile tests materials in initial state after performed. For both materials, HE resulted microstructure—formation un-equilibrium grain boundaries partition grains. What is more, a significant increase strength decrease elongation, mostly first degree deformation.
