The availability of the thermal diffusivity values, α, of alloy liquids and their glassy states is very limited at the present time, although the thermal diffusivity values of alloy liquids might have a close relationship with their glass-forming ability. Thus, the purpose of this work is to determine the thermal diffusivity values of three particular alloys, Pd 40Cu30Ni10P20, Pd 40Ni40P20, and Pd40Cu 40P20, in the liquid state, systematically obtained using a laser flash method involving a novel sample cell. In the liquid state, the thermal diffusivity value of the Pd40Cu30Ni 10P20 alloy showing an outstandingly high glass-forming ability is lower than that of the Pd40Ni40P20 alloy and it is much lower than that of the Pd40Cu40P 20 alloy which has a low glass-forming ability. With respect to the thermal diffusivity values of the Pd40Cu30Ni 10P20 alloy, a positive temperature dependence was certainly obtained in all conditions: The glassy, supercooled liquid, and liquid states.
