Influence of Phase Composition and Homogenization Temperature on Magnetic Characteristics of High-Entropy Alloys of the CoCrFeNiAlx System
Source abstract
Abstract
Abstract High-entropy alloy of the CoCrFeNiAlx system (x = 0.3, 0.6, 0.8, 1.0) was obtained by powder sintering. The influence of homogenization temperature (900, 1000, and 1100°C) on microstructure, phase composition, microhardness, and magnetic properties of the alloy was investigated. It was found that microhardness, saturation magnetization, and maximum magnetic permeability increase with increasing homogenization temperature. The changes in magnetic characteristics correlate with the phase composition. The results obtained confirm the possibility of using magnetic methods to evaluate structural changes in high-entropy alloys of this system.
