    • PROBLEM TO BE SOLVED: To provide an composite amorphous metal object, and to provide a method for producing the composite amorphous metal object. SOLUTION: In the composite metal object, crystalline ductile metal particles exist in an amorphous metal matrix. An alloy is heated above its liquidus temperature. Upon cooling from the high temperature melt, the alloy chemically partitions, forming dendrites in the melt. Upon cooling the remaining liquid below the glass transition temperature, it freezes to the amorphous state, producing a two-phase microstructure containing crystalline particles in an amorphous metal matrix. The ductile metal particles have a size in the range of from 0.1 to 15 μm and spacing in the range of from 0.1 to 20 μm. Preferably, the particle size is in the range of from 0.5 to 8 μm and spacing is in the range of from 1 to 10 μm. The volume proportion of particles is in the range of from 5 to 50% and preferably 15 to 35%. Differential cooling can produce oriented dendrites of ductile metal phase in an amorphous matrix. Examples are given in the Zr-Ti-Cu-Ni-Be alloy bulk glass forming system with added niobium. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:提供复合非晶金属物体,并提供一种复合非晶金属物体的制造方法。 解决方案:在复合金属物体中,晶体延性金属颗粒存在于非晶金属基体中。 将合金加热至液相线温度以上。 在从高温熔体冷却时,合金化学分隔,在熔体中形成枝晶。 将剩余液体冷却至低于玻璃化转变温度时,其冻结至非晶态,产生在非晶金属基质中含有结晶颗粒的两相微结构。 延展金属颗粒的尺寸在0.1至15μm的范围内,间距在0.1至20μm的范围内。 优选地,粒度在0.5至8μm的范围内,并且间距在1至10μm的范围内。 颗粒的体积比例在5至50%,优选15至35%的范围内。 差分冷却可以在无定形基质中产生延性金属相的取向树枝状晶体。 在具有添加铌的Zr-Ti-Cu-Ni-Be合金块状玻璃形成系统中给出了实施例。 版权所有(C)2010,JPO&INPIT
