    摘要:

    采用按比例混合合金粉末壓制成圓柱試樣，然后用低溫?zé)Y(jié)和隨后機(jī)械球磨的方法制備了非晶態(tài)的Mg2Ni型合金。研究了燒結(jié)和球磨對(duì)不同Mn含量的Mg2Ni型合金的相形成過(guò)程及電化學(xué)性能的影響。實(shí)驗(yàn)表明：在Mg2Ni中采用第三組元Mn對(duì)Mg進(jìn)行適量的替代后，通過(guò)燒結(jié)及球磨方法可以獲得均勻的非晶相；微量替代可有效地提高其放電容量：隨替代量的增加，合金最大放電容量和高速放電能力降低，而充放電循環(huán)穩(wěn)定性提高。

    Abstract:

    Amorphous Mg2Ni-based alloy powder was prepared by sintering and subsequent ball milling with Ni. The effects of substitution of Mn for Mg on phase formation and electrochemical discharge performance of Mg2Ni-typed alloys were studied. The results show that partial substitution of Mn for Mg in Mg2-xMnxNi (x=0.1,0.2,0.3,0.4) alloys can obtain homogeneous amorphous alloys and can increase the discharge capacity effectively compared with Mg2Ni alloy. As the content of Mn substitution increases, the maximum discharge capacity and rate discharge capability of Mg2Ni-typed alloy decline and the cycling durability upgrades.
