摘要：
This study reported the significant enhancement in corrosion resistance and the reduction in corrosion anisotropy of an icosahedral phase-reinforced Mg-8Li-6Zn-1Y alloy by using the cross-rolling (CR) instead of the traditional unidirectional-rolling (UR). Corrosion rates of RD-ND, TD-ND and RD-TD surfaces of the UR sample were 19.20, 17.03 and 10.82 mm/y, whereas those of CRD1-ND, CRD2-ND and CRD1-CRD2 surfaces of the CR sample were 9.07, 8.90 and 7.18 mm/y. Failure analysis indicated that the high corrosion resistance and weak corrosion anisotropy of the CR-processed sample were ascribed to the uniform distribution of I-phase particles and small aspect ratio of alpha-Mg phase.
