试样在超塑性变形时产生的伸长率与晶界宽度有密切联系。
Elongation of the sample during superplastic deformation has a close relation with grain boundary width.
晶粒长大到微米尺度时，变形机制主要是位错协调的晶界滑移和位错滑移塑性。
The main deformation mechanisms are dislocation accommodated grain boundary sliding and dislocation slip plasticity when the grains grow to micro size.
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。
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.
