| Research Abstract |
High density of Al_9FeNi nano-phase was precipitated in Al primary phase by simple plastic deformation, e.g. forging and rolling, of Al ingots embedded with TiNi powder at room temperature, without aging. Those nanoprecipitates were formed by eutectic reaction between Al and Al_9FeNi phases after local melting in the vicinity of the embedded TiNi powder during plastic deformation, where local temperature elevation was induced by enthalpy of mixing of Al and embedded powder.
