Abstract

Amorphous alloys have high tensile strength and easy soft magnetization, and are corrosion-resistant. As conventional amorphous alloy strips are mainly produced by the single rolling method, their thickness is less than 100 µm and their width is less than 200 mm. By combining ultra-rapid cooling, large-scale thermal spraying and warm rolling, the world’s first ever amorphous alloy strips were produced with thickness exceeding 300 µm and width exceeding 300 mm.
