    摘要:

    用高能球磨法制備Ti50Ni22Cu25Sn3非晶粉末,并研究球磨工藝參數(shù)對(duì)Ti50Ni22Cu25Sn3非晶形成過程的影響。結(jié)果表明,球磨轉(zhuǎn)速以及磨球直徑對(duì)Ti50Ni22Cu25Sn3非晶相的形成效率具有十分重要的影響。較高的轉(zhuǎn)速和合適的球徑能有效促進(jìn)該Ti基合金的非晶化,縮短合金非晶化的時(shí)間,當(dāng)轉(zhuǎn)速為400 r/min,球料比為20:1時(shí),球磨時(shí)間約為30 h后,可得到完全的Ti50Ni22Cu25Sn3非晶粉末

    Abstract:

    High energy ball milling method was employed to prepare the amorphous Ti50Ni22Cu25Sn3 alloy powders, and the effects of the ball milling parameters on the formation of the amorphous alloy were investigated. Results indicate that the rotation speed and ball diameter have a significant influence on the formation efficiency of the amorphous phase. High rotation speed and proper ball diameter can shorten the time to form the amorphous phase. At the rotation speed of 400 r/min and the mass ratio 20:1 of the ball to the powders, the completely amorphous Ti50Ni22Cu25Sn3 alloy powders can be obtained after ball milling for 30 h
