【摘要】 本文主要研究了不同稀土元素对工业纯镁显微组织及显微硬度的影响,结果表明:不同量的Ce、Y、Nd、Dy稀土元素加入工业纯镁中可使合金的显微组织和显微硬度发生极大的变化。其中Mg-Re合金中,当Re含量达10%时组织细化效果最为明显,显微硬度可达90-100HV。Mg-0.5Y-Re合金当Re含量达5%时组织细化效果已非常明显,其中Mg-0.5Y-5Dy合金的显微硬度可达102HV。更多还原

【Abstract】 The effects of different Re elements on microstructure and microhardness of industrial pure Mg were investigated.The results showed that the microstructure and microhardness of Mg changed remarkably after the different additions of Ce,Y,Nd or Dy element.For Mg-Re alloy,the refinement effect was best and the microhardness reached to 90-100HV when the Re content was 10wt.%.For Mg-0.5Y-Re alloy,the refinement effect was excellent when the Re content was 5wt.%.Thereinto,the microhardness of Mg-0.5Y-5Dy alloy reached to 102HV.更多还原
