【摘要】 用电子探针微分析方法测定了 Fe-Mn-Al 系富 Fe 角的五个等温截面,研究了碳对相界的影响。800℃时得到了α+γ+β三相区。碳能使γ相区扩大,高温时效果更显著。更多还原

【Abstract】 The phase equilibria of Fe corner in Fe-Mn-Al tenary system at five tempera-ture was investigated by means of electron probe microanalysis.The effect of carbon on the ex-tend of phase regions was also studied.A region of triple phases(α+β+γ)was found at 800℃.Itfollows that the γ phase region was extend when carbon existed in the alloy and this effect be-comes more notable at high temperature.更多还原
