Effect of Annealing on Microstructures and Hardness of Al1.5CrCuFeMnTi High Entropy Alloy AITranslate
Abstract AITranslate
To study the effect of annealing treatment on microstructures and hardness of Al1.5CrCuFeMnTi high entropy alloy,the as-cast alloy was prepared by vacuum arc melting,and the morphology,crystal structure,composition distribution and hardness of the alloy obtained under isothermal annealing treatment at different temperatures were characterized by using methods of X-ray diffraction,scanning electron microscope and Vickers hardness tester.The results show that the as-cast Al1.5CrCuFeMnTi alloy is composed of an ordered and a disordered solid solution with a body-centered cubic structures,which forms a typical dendritic structure,and the characteristic of modulated structure is also observed in as-cast alloy.After annealing at 945℃,a Laves phase rich in Al,Cr and Mn with complex structure is formed.After annealing at 980℃,the Laves phase is transformed into FCC solid solution with Cr as matrix.Annealing treatment is conducive to the release of residual internal stress in as-cast alloys,which reduces the hardness of the alloys to about HV450.
