- Abstract
- In this work, the effects of homogenization annealing temperature of Al0.5CoCrFeMnNi HEA on cracking during cold-rolling were investigated. AINi B2 phases were formed by low-temperature homogenization and affected the cracking phenomenon during cold-rolling. X-ray diffraction, microstructure, and composition analyses and thermodynamic calculations were conducted to identify the crystal structure of the alloy after the homogenization annealing treatment. The phase fraction and hardness of the homogenized alloy confirmed that the formation of the AINi B2 phase induces cracking during cold-rolling of the AlosCoCrFeMnNi alloy. High-temperature annealing for homogenization of the alloy is recommended to prevent cracking during cold-rolling. (C) 2017 Elsevier B.V. All rights reserved.
