| Resumo | |
High-entropy alloys (HEAs) are defined as alloys containing five or more major elements in atomic fractions ranging from 5 to 35%at. Despite the presence of a large number of components, CrMnFeCoNi HEAs show simple FCC crystal structure.This work reports the effects of cold rolling on the final microstructure and the mechanical properties of a CrMnFeCoNi HEA processed by spray forming and deformed to 30, 50, 90 and 146% of true strain. The results presented an alloy with excellent workability and exhibited a large work hardening capacity in cold rolling. It is concluded that the main deformation and hardening mechanisms during cold work are associated with the nanotwinning deformation of this alloy. (AU) | |
