The quasicrystalline alloy which contains the element aluminum present dispersion of particles in nanometric scale that exhibit high values of mechanical strength at room temperatures and high temperatures. The quasicrystalline solids have no crystallographic conventional symmetrical structures; but they are constituted by a unit cell with periodic repetition in space and ordination mode, intermediate between periodic phases and crystalline phases amorphous non-crystalline. The process of Mechanical alloying, a technique of powder metallurgy developed in the 60's, it was established as a viable processing method in the solid state to produce various quasicrystalline phases metastable and stable. The interest in obtaining this material is du...
