抄録/ポイント： AZ91合金粉末の粒径を最適化水素化-不均化-再結合過程(HDDR)により100から160μmに約15nmに微細化した。HDDRプロセス中のAZ91合金粉末の相および微細組織変化に及ぼす温度,水素圧力と処理時間の影響を,X線回折,光学顕微鏡,走査電子顕微鏡および透過型電子顕微鏡により系統的に調べた。ナノ結晶Mg合金粉末を調製するための最適HDDRプロセスは真空中で3時間,350°Cで12時間と脱水素のための4MPaの水素圧力下での350°Cの温度でhydridingである。修正未反応コアモデルをHDDRプロセス中の結晶粒微細化の機構を記述するために導入した。Copyright 2017 Elsevier B.V., Amsterdam.
