Abstract Amorphous alloys are a kind of material that possess high Young's modulus and preferable material forming ability. Among all the amorphous alloys, palladium-based amorphous alloys form a system that is highly representative. In order to study the impact of preparation process and changes in composition on the thermal transfer properties of the palladium-based amorphous alloys, we concentrated on two kinds of palladium-based amorphous alloys Pd40Ni10Cu30P20 and Pd43Ni10Cu27P20 prepared by the plastic deformation method in this research. The thermal conductivities, electrical conductivities and Seebeck coefficients of these palladium-based amorphous alloys have been measured using the steady state T-type method, the standard four-probe method and the AC heating-DC detecting T-type method respectively. The results showed that in the palladium-based amorphous alloys of the same preparation method, the thermal conductivities and the electrical conductivities are highly sensitive to the change in composition, and the Seebeck coefficients are less sensitive to change in composition. The results also showed that in the palladium-based Pd40Ni10Cu30P20 amorphous alloys of the same composition, the electrical conductivity of the sample prepared by plastic deformation is almost identical to the sample prepared by melt cooling, and the thermal conductivity of the sample prepared by plastic deformation is significantly greater than the sample prepared by melt cooling.
