文摘

The AlxSi0.2CrFeCoNiCu1−x alloys were prepared by arc melting (Ix) and injection casting assisted by liquid nitrogen (Rx). The x range of the Rx alloys with dual-phase structure is smaller than that of the Ix alloys. The Rx alloys exhibited finer grain size and spinodal decomposition (SD) plates. The Rx alloys showed higher hardness and yield stress.
