twin-crystal的意思|示意

At the time of deformation reached 40%, the appearance of the crystal changed greatly: the size refined, boundary turned clear, second phase disappeared and twin crystal structure appeared.

变形量为40%时，轧板的晶粒形貌发生了显著变化，晶粒变得细小，晶界清晰，第二相完全消失，并出现孪晶组织。

The cause may be related to the twin structure of KTP crystal.

产生原因可能与其双晶结构有关。

It is mainly because that dislocation slides easily within large twin crystal, which leads to the decrease of strength and the increase in plasticity.

主要是位错在大孪晶中易于移动，从而造成强度下降，塑性提高。
