Thermomechanical treatment of a Fe-Mn-Al alloy

Resumo

Analysis of the hardnees and the metalographic struture, show in a FeMnAl alloy the existence of a γ fase and a β precipitate, activitate by Si during the casting processes. During the recovery and recrystalisation temperatures there are the formation of fringes, coarsed grains of γ fase and β precipitate . The thermomechanical treatments give to the material excellent properties of mechanical resistance and good ductility, without the β collaboration.
