Descripción
Sumario:In the present study, the thermal stability and crystallization behavior of mechanical alloyed metallic glassy Al(82)Fe(16)Ti(2), Al(82)Fe(16)Ni(2), and Al(82)Fe(16)Cu(2) were investigated. The microstructure of the milled powders was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and differential scanning calorimetry (DSC). The results showed remarkable distinction in thermal stability of the alloys by varying only two atomic percentages of transition elements. Among them, Al(82)Fe(16)Ti(2) alloy shows the highest thermal stability compared to the others. In the crystallization process, exothermal peaks corresponding to precipitation of fcc-Al and intermetallic phases from amorphous matrix were observed.
