Study on the Ductility of Rapidly Solidified Fe3Al Inter-Metallic Compounds (Ⅱ)
-
摘要: 通過急冷凝固及加鉻合金化的方法,改善了金屬間化合物Fe3Al的室溫塑性。實驗結果表明:急冷凝固降低了合金有序度,細化了晶粒,而合金元素鉻的添加,使鐵鋁合金的室溫延伸率由2%提高到5.6%。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.
