【摘要】 通过急冷凝固及加铬合金化的方法,改善了金属间化合物Fe₃Al的室温塑性。实验结果表明:急冷凝固降低了合金有序度,细化了晶粒,而合金元素铬的添加,使铁铝合金的室温延伸率由2％提高到5.6％。更多还原

【Abstract】 The room temperature ductility of Fe3Al intermetallic compound has been improved by Cr addition and rapid solidificaton processing. The experimental results show that RSP decrease the grain size and the degree of order and 2%Cr addition increases the room temperature ductility from 2% to 5.6%, which may be associated with the increase of cleavage stringth.更多还原
