METHOD FOR MANUFACTURING A BALANCE FOR A TIMEPIECE

A process for producing a metal alloy balance wheel by molding, the process including the following steps: a) making a mold in the negative shape of the balance wheel, b) getting hold of a metal alloythat has a thermal expansion coefficient of less than 25 ppm/DEG C. and is able to be in an at least partly amorphous state when it is heated to a temperature between its glass transition temperatureand its crystallization temperature, c) putting the metal alloy into the mold, the metal alloy being heated to a temperature between its glass transition temperature and its crystallization temperature so as to be hot-molded and to form a balance wheel, d) cooling the metal alloy to obtain a balance wheel made of the metal alloy, e) releasing the balance wheel obtained in step d) from its mold. 本发明涉及一种通过模制制造金属合金摆轮的方法，所述方法包括以下步骤：a)制造为所述摆轮(1)的负形状的模具；b)获得热膨胀系数小于25ppm/℃并且当其被加热到在其玻璃化转变温度和其结晶温度之间的温度时能够处于至少部分非晶态的金属合金；c)将所述金属合金放入所述模具中，将所述金属合金加热到在其玻璃化转变温度和其结晶温度之间的温度，以便被热模制并形成摆轮；d)冷却所述金属合金，以获得由所述金属合金制成的摆轮(1)；e)将在步骤d)中获得的摆轮(1)从其
