Production of CoCu-NiAl Multi Component Alloys via Resistive Sintering

Multi component alloys emerge as a new research area in materials science and engineering in recent years. In this work, three different compositions of Al-Co-Cu-Ni elements powders with high purity (99,5 wt.%) and particle size of 45 μm (-325 mesh) were used to produce multi component alloys via Electric Current Activated (Assisted) Sintering (ECAS) process at 2200 Amper for 90 seconds. Microstructures of sintered samples were investigated by scanning electron microscopes (SEM), phases in samples were analyzed by XRD and their hardness was measured by Vickers hardness tester ranged from 288 to 422 HV.
