Question

谁可以帮我翻译一下啊，谢谢了

? Three -stage strain hardening behavior has been
observed in a typical T WIP steel. In stage ?, pla -
nar dislocation structure is the main deformation
mode in the early stage of plastic deformation, while
deformation twinning becomes the dominant mode in
the later stages of deformation. In stage ?, primary
twinning occurs and twin boundaries act as barriers
to dislocation motion during plastic deformation,
leading to the local stress concentration and strain -
hardening behavior. In stage ?, the secondary
twinning system is activated under higher strain.
Besides the twin -dislocation interaction can lead to
the local strain hardening, twin -twin interactions
may also contribute to the additional strengthening
during deformation by secondary twins generating
on the { 111} planes in the obstacle twins during
twin -twin interactions, which needs more stress ac -
cumulation in front of twin boundaries and contrib -
utes to the increase of strain hardening rate. Large
necking free elongation is obtained by local harden -
ing which is achieved by sequentially generated de -
formation twinning system, contributing to the
? Twin Induced Plasticity? effect.

Answer 1

？三阶段的应变硬化行为被在一个典型的T WIP钢。在舞台上吗？中国人民解放军，NAR的位错结构的塑性变形的早期阶段的主要deformationmode，whiledeformation孪生成为占主导地位的模式在变形的后期阶段。在舞台上吗？primarytwinning，发生和孪晶界的位错运动行为障碍中的塑性变形，导致局部应力集中和应变硬化行为。在舞台上吗？的secondarytwinning系统被激活，在较高的应变。除了孪生位错的相互作用可导致局部应变硬化，双双interactionsmay也有助于额外的strengtheningduring变形的二次孪晶generatingon的{ 111 }飞机在障碍的双胞胎duringtwin双胞胎之间的相互作用，这需要更多的应力累积在交流双边界和与前执行的应变硬化率的增加。largenecking自由伸长是通过局部硬化-这是由顺序产生的德-形成孪晶系统实现的，对吗？孪生诱发塑性？的影响。
