Abstract:
(Al90-Ni8-Zr2)(100-x)Mmx alloys were rapidly solidified by using melt-spinning technique to examine the effect of Misch metal content on microstructure, thermal and mechanical properties. The resulting melt-spun ribbons were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, differential scanning calorimetry, and Vickers microhardness tester. Al90Ni8Zr2 alloy consists of amorphous and nano-crystalline α- Al with 30nm size phases. Other ribbons were completely amorphous, so glass forming ability increased by adding Mm. The change in microhardness is discussed and concluded that the higher the Misch-metal content, the higher thehardness of the ribbons
