| Research Abstract |
The Al9FeNi phase was formed in Al ingots embedded with TiNi powder by plastic deformation, e.g. forging and rolling, at room temperature. The reaction between the Al matrix and TiNi powder was initiated by plastic deformation, and the Al and the TiNi powder locally melted at the boundary, followed by rapid solidification with forming Al9FeNi. In order to study the effect of the Al9FeNi precipitates on mechanical properties of the Al ingots, Al plates were covered by FeNi electrodeposition and they were heated near the surface of the Al by high-frequency induction heating, and the Al9FeNi phase was precipitated. The Vickers' hardness was increased for 20% by formation of the Al9FeNi phase. The surface of Mg-12Al ingots were also covered by evaporated Ni and they were subjected.
