Abstract
The effect of grain size on mechanical properties and corrosion resistance of Ni62Cr10V28 MEA was investigated. The findings indicated that grain refinement significantly enhanced the corrosion resistance of the investigated alloys, attributed to the distinctive characteristics of grain boundaries and the fast formation rate of passive film. Additionally, the investigated alloys demonstrated a yield strength ranging from 518.7 MPa to 714.2 MPa, accompanied by an elongation ranging from 46.29 % to 50.48 %, thereby attaining a superior strength-ductility balance. Overall, grain refinement demonstrates a favorable synergistic effect on both mechanical properties and corrosion resistance.
