1) irregular upper bainite
非常规上贝氏体
1.
The experimental results show that, when the cooling rate after austenitization is between 20℃/s and 50 ℃/s and isothermal time is between 80 s and 1 200 s, the irregular upper bainite microstructure can be obtained.
实验结果表明,当奥氏体化后的冷却速度为20￣50℃/s、等温时间为80￣1200s时,获得非常规上贝氏体组织,并呈现由单一α相组成的短棒状,晶格常数与平衡态α相不同,晶格呈膨胀状态,相变具有非完全扩散的特征。
2) irregular low bainite
非常规下贝氏体
1.
The experimental results show that only when the following conditions which are fast cooling after austenitization and isothermal time from 80 s to 1200 s are provided can the irregular low bainite be obtained.
实验结果表明,当奥氏体化后的冷却速度接近临界冷速(60℃/s)、等温时间大于孕育期(80 s)且在20 min以内短时等温获得非常规下贝氏体组织,其光学显微组织形态呈现由单一α相组成的短针状,晶格常数和平衡态α相不同,其值为2。
3) Upper bainite
上贝氏体
1.
The results show that the appearance of Widmanstatten structure,upper bainite and martensite in the structure of 20MnSi HRB is the main cause making the yield point disappear.
结果表明 :2 0 Mn Si热轧带肋钢筋中出现的魏氏组织、上贝氏体及马氏体组织是使屈服点消失的主要原因。
2.
The main reason why mechauical propcrties of qutnched and tem-Pered hcavy part or 35CrMo steel,such as impact toughness and so on,are impossiblc to meetthe requirements is regarded as tbe presentation or the upper bainite in its microstructure.
本文总结了多年来有关35CrMo钢热处理的经验，认为35CrMo钢制大件调质处理后冲击韧性等力学性能达不到要求的原因主要是组织中出现较大量的上贝氏体。
3.
The results show that upper bainite and grain boundary segregation of Si element result in embrittlement of the oil cylinder.
结果表明,上贝氏体和Si元素的晶界偏聚导致油缸变脆。
4) upper metabainite
准上贝氏体
1.
An investigation of the interfacial misfit dislocation at bainitic ferrite(BF)retained austenite(Ar) interface of upper metabainite has been undertaken in a BZ30 Sicontaining steel by means of weakbeam darkfield TEM.
运用透射电镜研究了含Ｓｉ钢准上贝氏体中贝氏体铁素体（ＢＦ）／残余奥氏体（ＡＲ）的界面错配位错，发现是混合型位错，使得界面能沿其法线方向作滑移运动，表明贝氏体可以切变形成。
5) high bainite
上贝茵体，上贝氏体
6) rod-like upper bainite
短棒状上贝氏体
1.
With the increase of isothermal time,new rod-like upper bainite generates at the side of the first rod,so that the upper bainite has thick rod-like micromorphology.
结果表明,380℃短时等温获得短棒状上贝氏体组织;随等温时间延长,新的上贝氏体小棒于原贝氏体棒两侧形成,上贝氏体小棒的平行排列使上贝氏体变为粗棒;随等温时间的进一步延长,粗棒状上贝氏体平行排列组合近似羽毛状;长时间等温,贝氏体碳化物析出使上贝氏体组织具有羽毛状形貌。
