Abstract

The thicknesses of six different metal foils were adjusted to approximately equal atomic weights, and they were stacked and rolled to form a rod. The rod was attached to the chuck of a drilling machine and was rotated and pressed against an Al₂O₃ substrate to form a Ti-Zr-Hf-Ta-Mo-Mg alloy film. The metal foil elements were evenly distributed in the films. The crystallinity of the films was low due to the strong processing. The elastic modulus and nanoindentation hardness of the film formed on an unheated substrate were 189 ± 45 GPa and 14 ± 5 GPa, respectively. The adhesion strength was over 1.3 MPa; thus, the film was strongly bonded to the substrate.
