Resumen:
Mg alloys have attracted high interest because of its outstanding specific strength. Automobile andairplane industries are constantly improving the strength-to-weight ratio of their structural materials.Particularly AZ31B alloy (Mg + 3 wt.% Al, 1 wt.% Zn and 0.2?0.5 wt.% Mn) has achieved a largediffusion with those purposes. Mn addition helps on the refinement of microstructure conferring animprovement on mechanical properties. Meanwhile, grain size reduction by Severe Plastic Deformation(SPD) has been also widely applied to improve mechanical properties. Among the many SPDtechniques, the one known as Equal Channel Angular Sheet Drawing (ECASD) is appropriate tointroduce large deformations on the Surface of materials, without changing the section of thematerial, except for a small section reduction. The main purpose of the technique is the productionof sheets with very large surface hardness with a ductile core while expending just small amounts ofextra deformation energies.
