摘要: Abstract The misch metal-iron (MM-Fe) system has been investigated in the temperature range from 700 to 1150 °C at iron-rich end (up 33.3% RE, where RE is total rare earth content of MM). Two intermediate phases, Fe 17 2 and two broad three-phase fields, α - + liquid , exist region MM-Fe system. γ-Fe phase cannot be retained by quenching alloys high temperature. solid solubility iron less than 0.5 at.%.
