Abstract

Eutectic multi-principal element alloys show great promise due to their exceptional castability, unique near-equilibrium microstructure, and controllability. In this study, a novel copper-containing Cu42.3Ni30Si15Al12.7 eutectic multi-principal element alloy was designed and investigated. The microstructure of the alloy is composed of primary phase Ni2Si and eutectic phase (FCC(Cu) + BCC(NiAl)). The eutectic reaction temperature is 1004°C. Understanding the solidification process is crucial for optimising solidification parameters and subsequent annealing. The as-cast Cu42.3Ni30Si15Al12.7 alloy exhibits high micro-hardness (400 ± 2.4 HV) and compressive fracture strength (1511 MPa)
