  1. The eutectic crystal al3fe often is " needle " shape or short line shape but the shape of primary crystal al3fe is relative to the adding amount of fe powder and the temperature of heat preservation stirring. while the adding amount of pure fe powder is few and the temperature of heat preservation stirring is higher than the temperature of liquidus of al - fe binary alloys equilibrium phase diagram, the reaction synthetical primary crystal al3fe exhibits short worm shape

    加入量少,保溫攪拌溫度在al - fe二元合金液相線以上,則形成的初晶al _ 3fe呈短蠕蟲狀; fe加入量大,保溫溫度在液相線以上,初晶al _ 3fe以平面方式生長,復合材料中的初晶al _ 3fe呈塊狀或粒狀,尺寸較大( 10 m以下) 。
