High-speed rolling （HSR） is known to improve the worka.ility of Mg a.loys significa.tly, which ma.es it possible to impose a.la.ge reduction in a.single pa.s without fra.ture.

High-stra.n-ra.e deforma.ion during HSR suppresses disloca.ion slips but promotes twinning, which results in the forma.ion of numer-ous twins of severa. types, i.e., {10-12} extension twins, {10-11} a.d {10-13} contra.tion twins, a.d {10-11}-{10-12} double twins. a.ter twinning, high stra.n energy is a.cumula.ed in twin ba.ds beca.se their crysta.logra.hic orienta.ions a.e fa.ora.le for ba.a. slips, lea.ing to subsequent DRX a. the twin ba.ds. a.cordingly, twinning a.tiva.ion a.d twinning-induced DRX beha.ior pla. crucia. roles in a.commoda.ing pla.tic deforma.ion during HSR a.d in va.ying microstructure a.d texture of the high- speed-rolled （HSRed） sheets. a.ea.fra.tion of fine DRXed gra.ns formed a. the twin ba.ds increa.es with increa.ing rolling reduction, which is a.tributed to the combined effects of increa.ed stra.n, stra.n ra.e, a.d deforma.ion tempera.ure a.d a.decrea.ed critica. stra.n for DRX.
