| 1. | The performance consistence of ab5 alloy in mass production is influenced by not only the quenching condition , but also the impurities such as fe , mg in mischmetal and the melting technology including the unit output , melting temperature and time , atmosphere , furnace frequency etc 合金性能波动除受浇铸时的冷却条件影响外,还与稀土原料中铁、镁等杂质及熔炼工艺因素(包括单位产量、熔炼温度、时间气氛及炉频等因素)有关。 |
