Abstract
- The kinetics of the glass transition and the crystallization behavior of Ti–Cu–Ni–Sn–M (M=Zr,Mo,Ta) glassy alloys were investigated by differential scanning calorimetry and x-ray diffraction. The glass-forming ability (GFA) of the glasses was analyzed in terms of the fragility concept and the width of the supercooled liquid region. The Ti-base glasses studied were found to have lower GFA than Zr, Pd, La, Fe, Mg-base bulk metallic glasses (BMGs), but to be comparative GFA to Ni- and Au-base BMGs. Higher Mo content or higher Ti–Ta content in the alloys lowers the GFA. The chemical complexity and multiphase crystallization requiring long-range atomic diffusion may contribute to the thermal stability of the supercooled liquid against crystallization. The products of crystallization of the glasses include bcc β-Ti(M) solid solution and Ti[sub 2]Ni and Ti[sub 2]Cu intermetallics. © 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]
