In order to expand the application prospects of LZ91 magnesium alloy, improve its tensile strength and yield strength. In this paper, the asynchronous rolling and cumulative rolling technology are combined in the large plastic deformation technology, and the LZ91 magnesium alloy after coating the aluminum foil by the asynchronous accumulative roll bonding is performed. The analysis shows that the asynchronous accumulative roll bonding technology accumulates a large amount of deformation energy storage inside the material through large plastic deformation, and refines the grain to the micro-nano level, which increases the strength of the LZ91 magnesium alloy by 86% and the hardness by 63.97%. Improve the internal structure and application performance of the material. |
