The experimental results show that strain rate doesn't affect the fracture mechanism of intragranular dimple and mainly dislocation slipping;the tensile strength is increased slightly along with the increase of strain rate,however,the elongation doesn't decrease in general which is decreased firstly and raised later with the increase of strain rate,the high s.
结果表明,应变速率对10Ni5CrMoV钢的断裂方式没有影响,拉伸试样均为塑性断裂,断裂微观机制主要是位错滑移;抗拉强度随应变速率增加而略有增加;伸长率随应变速率的增加先下降后上升,但总体无降低;高应变速率并未造成该钢的脆化。
Through the analyses of the X-ray diffraction data and the corresponding crystallography, it was found that during the first pass of ECAP, the main deformation mode of α phase is {1011}(1012} twinning, while during the following passes the main deformation mode is dislocation slip.
α相在第1道次ECAP过程中主要的变形方式是{1011}〈1012〉孪生,在随后道次的ECAP过程中主要变形方式为位错滑移,变形方式的转变主要是由于ECAP造成的组织细化效应;对于β相,各道次ECAP的主要变形方式均为位错滑移。
Twinning and dislocation slip have been proven to be the dominant model of plastic deformation when the temperature is bel.

It is of no significance that gold is transported from the inside of pyrite in which gold atoms diffuse via defects such as dislocations if there is no dislocation sliding in the pyrite.
分析了高温高压高应变速率条件下黄铁矿中的晶格金迁移的动力学机制后认为 :黄铁矿晶格中的金原子趋向于向位错等缺陷处扩散 ;在无位错滑移的情况下 ,晶格金原子在位错线等缺陷中扩散的扩散方式对其从黄铁矿内部迁移出来无实际意义 ;在高温高压高应变速率 [( 1 0 - 8～ 1 0 - 4) /s]条件下黄铁矿变形以位错滑移为主 ,金原子伴随着位错滑移一起迁移 ,最终迁移进入裂隙 ,增加了与成矿流体接触的机会。
25, respectively, GBS and dislocation creep appeared to dominate the deformation process, consistent with the SEM examination.
