ABSTRACT:
An amorphous alloy which is resistant to hot corrosion in sulfidizing and oxidizing atmospheres at high temperatures, consisting of at least one element selected from the group of Al and Cr and at least one element selected from refractory metals of Mo. W, Nb and Ta, a portion of the set forth refractory metals being allowed to be substituted with at least one element selected from Ti, Zr, Fe, Co, Ni and Cu. The addition of Si further improves the alloy's oxidation resistance.
