Method of producing amorphous alloy excellent in flexural strength and impact strength

摘要

A molten alloy was pressure-solidified under a pressure exceeding one atmospheric pressure to eliminate casting defects. The molten alloy was solidified by applying a cooling rate difference to the surface and the interior of the molten alloy to allow a compressive stress layer to remain on the surface of the amorphous alloy ingot and a tensile stress layer in the interior portion. Thus, a amorphous alloy sheet having a thickness of 1 mm or more and excellent in bending strength and impact strength is obtained.
