Abstract
The invention discloses a composite forming method of an amorphous alloy and a non-amorphous alloy. The composite forming method comprises the following steps: A, preparing a non-amorphous alloy, placing the non-amorphous alloy on a fixed position; B, preparing an amorphous alloy, fixing the amorphous alloy around the non-amorphous alloy; and C, applying a pressure to the non-amorphous alloy at a temperature between a glass transition temperature and a crystallization temperature of the amorphous alloy to ensure that the amorphous alloy is in full contact with the non-amorphous alloy so as to form a composite of the amorphous alloy and the non-amorphous alloy. According to the composite forming method, by mainly using the characteristic that the amorphous alloy has superplasticity in an undercooling liquid phase region, the amorphous alloy is softened to deform by means of pressurizing at a temperature of the undercooling liquid phase region, so that the preset non-amorphous alloy is wrapped or otherwise bound together, the binding property is stable; meanwhile, the composite forming method is low in requirement of equipment and process; and the obtained product can achieve a user state without complicated processing in the subsequent process, and is suitable for volume production.
