RELATIONSHIP BETWEEN ORDER DEGREE INTERCEPTED AND MECHANICAL PROPERTIES OF Fe3Al

Abstract

Abstract: The glide energy B2-type and DO3-type in Fe3Al are calculated based on the empirical electron theory of solids and molecules (EET); the results indicate that B2-structure exhibits good ductility properties and low strength at ambient temperatures. The long-range-order intermetallic Fe3Al is investigated by order degree intercepted (quenched) technique. The results of XRD and compression-resistance show that Fe3Al with an imperfectly ordered B2 structure after order degree intercepted has low strength and low stiff. The mechanical properties are improved.

Key words: Fe3Al, Glide energy, Mechanical properties, Order degree intercepted
