The coarse needle-like or nubby Al9FeNi phase existed in the cast microstructure of high content Fe and Ni alloy 2618(2#). After hot extrusion, it was broken into coarse multi-angle Al9FeNi particles. The contents of Fe and Ni have no effect on aging characteristic and the hardness of the alloy after aging.

含锆的高铁、镍2618合金经熔体高温过热处理后(4#)，在合金铸态组织中获得均匀细小的针片状Al_9FeNi相，热挤压后获得均匀细小的颗粒Al_9FeNi相；弥散Al_3Zr粒子的存在可使2618合金得到细小的再结晶晶粒组织，该合金既可获得较高的高温强度，还可获得较高的延伸率。

The process of three-step countercurrentleaching is presented, in the first leaching step Fe as leading impurity inthe matte is leached priorly, Co and Ni are enriched in the residue of thefirst step and then are leached in the second leaching step with a lowconcentration acid, the residue from the second step containing hardleaching Fe, Co and Ni are leached with a high concentration sulfuricacid in the third step, and Cu stays in the final resude, the leachate of thethird leaching step is diluted and divided into two parts as the leachantsto the first and second leaching step.

在此基础上，提出了三段逆流选择性浸出技术：即第一段用低酸优先浸出钴冰铜中杂质铁，将钴镍富集到第一段的浸出渣中，第二段再用低酸浸出渣中部分钴镍，第三段用高酸浸出第二段渣中难浸的钴镍铁，将铜留在最终的浸出渣中，第三段浸出液经稀释，分流，分别返回至第一段，第二段作低酸浸出介质。
