Abstract: The Ti_1.4V_0.6Ni ribbon alloy containing icosahedral quasicrystal is prepared by melt-spinning technique, and the Ti_40.33Zr_40.33Ni_18.34 icosahedral quasicrystal powders are prepared by mechanical alloying. Both samples are annealing in a vacuum furnace. DSC trace obtained during continuous heating to 1300°C show a distinctly broad exothermic peak between 100°C and 1000°C for the Ti_1.4V_0.6Ni alloy, two sharp exothermic peaks between 100°C and 700°C for the Ti_40.33Zr_40.33Ni_18.34, respectively. The magnetic behavior results demonstrated the Ti_1.4V_0.6Ni ribbon alloy exhibited higher ferromagnetic properties than those of Ti_40.33Zr_40.33Ni_18.34 powders both at 15 K and 300 K. The specific heat capacity of two the sample increase when the temperature increase from 400 to 650°C.
