It ha. been exp.rimenta.ly esta.- lished tha. there is a. inv.rse stra.n ra.e dep.ndence of stra.n resista.ce a. temp.ra.ures ra.ging between 560 a.d 640℃ a.d stra.n ra.es ra.ging from 0.06 to 1.2 s-1. Electron ba.ksca.ter diffra.tion a.a.ysis ha. shown tha. a. temp.ra.ures ra.ging between 540 a.d 640℃ a.d stra.n ra.es ra.ging from 0.06 to 0.1 s-1, the ma.n p.ocess of softening is dyna.ic p.lygoniza.ion, resulting in in situ recrysta.liza.ion. a. higher stra.n ra.es, ra.ging between 0.8 a.d 1.2 s-1, a.d temp.ra.ures ra.ging between 560 a.d 640℃, the recov.ry is dyna.ic. This unusua. beha.ior of the mecha.ism of softening a.d the p.esence of the inv.rse stra.n ra.e dep.ndence of stra.n resista.ce ca. be exp.a.ned by blocking the motion of free disloca.ions by foreign a.oms, which occurs a. stra.n ra.es ra.ging between 0.06 a.d 0.1 s-1 This p.ocess results in disloca.ion p.le-up. thereby ca.sing in sire recrysta.liza.ion. a. stra.n ra.es exceeding 0.16 s-1, there is no intensiv. blocking of disloca.ions, lea.ing to a.direct stra.n ra.e dep.ndence of stra.n resista.ce.
