孪晶界阻碍位错运动导致高的加工硬化率；
The twin boundaries act as strong obstacles to the dislocation motion, so lead to higher strain-hardening.
有序化形成第二相粒子后阻碍位错运动，提高合金强度。
It leads to form the second phase particle, which hinder dislocation motion and improve alloy intensity.
这两种相都能阻碍位错运动，对合金起到很好的强化作用。
All of the two phases can impede dislocation movement, also play a very important role for strengthening the alloys.
结果表明，弱界面有阻碍位错运动、转主裂纹扩展方向的作用，可形成分层断口。
The results showed that the weak interface can block the motion of the dislocations and change the propagation direction of the main crack, and result in forming lamella fracture surface.

蠕变期间，晶内碳化物阻碍位错运动，晶界碳化物“钉扎”晶界，阻碍晶界滑动，由此提高钢的蠕变抗力。
The carbides in the matrix prevent dislocation from moving, and pin effect of the carbides in the grain boundary keep grain boundary from sliding, and creep resistance of steel is improved.
