采用工业级的低纯Zr,通过稀土Y的微合金化作用,制备Cu46Zr46Al8非晶合金。结果表明:Y能有效提升Cu46Zr46Al8合金的玻璃形成能力,主要原因是Y能吸附液态合金中溶解的氧,起到晶化合金的作用。当Y的添加量为2at%,3at%时,效果最为明显。经过Y微合金化后的非晶合金的抗压缩断裂强度超过2GPa,高于用高纯原料制备的非晶,但是塑性明显下降。 Industrial grade low purity Zr is used to prepare Cu46Zr46Al8 amorphous alloy through the micro alloying of rare earth Y. The results show that Y can effectively enhance the glass forming ability of Cu46Zr46Al8 alloy. The main reason is that Y can adsorb dissolved oxygen in the liquid alloy and act as a crystallized alloy. When the addition of Y is 2at%, 3at%, the effect is the most obvious. After Y microalloying of amorphous alloy compressive breaking strength of more than 2GPa, higher than the raw material prepared with amorphous, but the plastic decreased significantly.
