Abstract

Novel (Ti33Zr33Hf33)70(Ni50Cu50)20Al10, (Ti25Zr25Hf25Nb25)70(Ni50Cu50)20Al10, and (Ti33Zr33Hf33)70(Ni33Cu33Ag33)20Al10 multicomponent amorphous alloys developed by equiatomic substitution transform into a nano-scale icosahedral phase upon devitrification. However, the decomposition sequence of the nano-scale icosahedral phase at higher temperatures is significantly different for each alloy. The occurrence of the Zr2Cu-type phase during the decomposition of the devitrified icosahedral phase can enhance the thermal stability of the icosahedral phase.
