In this investigation recrystallization in metals was first used to study the plastically-deformed zone induced by cold cracking in welds. 本试验首次采用再结晶显示金属内塑性变形区的方法观察分析了焊接接头中冷裂纹产生的塑性变形区域。
Dynamic recrystallization takes place in the weld nugget zone and fine grains are achieved. 焊核区发生动态再结晶,生成细小的等轴晶粒。
The model to predict the average grain diameter of austenite deformed in complete recrystallization zone was established by means of combination of data processing and theoretical deduction. 利用数据处理与理论推导相结合的方法建立了钢在完全再结晶区变形后奥氏体晶粒平均直径的预报模型。
Results show that no obvious recrystallization in heat affect zone means alloy Al-Mg-Sc is of great resistant to soften behavior in HAZ. 结果表明,基材热影响区没有发生明显的再结晶现象,证明Al-Mg-(Sc,Zr)合金具有很强的抗焊接热软化能力;
If the steel was rolled in partial recrystallization zone, the structure of mixed grain would appear to deteriorate the steel property, so the deformation should avoid from the partial recrystallization zone in reality. 但在部分再结晶区轧制时容易出现混晶组织恶化钢的性能,所以实际变形应该避开部分再结晶区域。
There exist a partly thermodynamic recrystallization, and superplastic grains appear in the thermo-mechanical affected zone. 机械热影响区存在部分动态再结晶和较明显的塑性变形晶粒。
Structure change during multipass deformation in partial recrystallization zone of austenite 奥氏体部分再结晶区多道次变形组织变化规律的研究
The preliminary research on dynamic recrystallization and chemical transformations of feldspar in a mylonite zone 糜棱岩带中长石的动态重结晶及化学成分变化的初步研究
The deformation and recrystallization in the shear zone are very strong. 剪切带内糜棱岩的塑性变形和恢复重结晶作用强烈。
The results showed that the low-temp toughness of weld metal could be improved markedly through the welding method of two beads per layer, so that the recrystallization occurred in the middle zone of weld. 结果表明:通过采用每层两道的焊接工艺,使对接焊缝中心部位全部发生重结晶,是焊缝金属低温韧性提高的关键。
