1) 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。
2) 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。
3) 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。
4) granular bainite
粒状贝氏体
1.
Effect of granular bainite in microstructure after welding on impact toughness for micro-calcium steel;
微钙钢焊后显微组织中的粒状贝氏体对韧性的影响
2.
Research on granular bainite of 12CrNi3 Steel;
12CrNi3钢粒状贝氏体的研究
3.

5) lath bainite
束状贝氏体
1.
The results show that a granular structure was obtained for the tested steel by furnace cooling,a mixture of granular structure and granular bainite was obtained by aluminim silicate fiber packing cooling,a little amount of granular bainite and lath bainite was obtained by air cooling.
结果表明 ,该钢随炉冷却时主要获得粒状组织 ,用硅酸铝纤维包冷时为粒状组织和粒状贝氏体的混合组织 ,空冷状态下的组织为少量粒状贝氏体和束状贝氏体。
6) zonal bainite
带状贝氏体
补充资料:奥氏体-贝氏体球铁
分子式:
CAS号:
性质:又叫奥-贝球铁。基体组织为奥氏体加贝氏体组织的球墨铸铁。这类球铁硅含量一般在1.4%~3.8%。含锰量小于0.5%,与普通球铁比较硅偏高、锰偏低。通过调节化学成分与热处理获得理想的奥-贝球铁的基体组织为针状贝氏体或无碳贝氏体一富碳奥氏体。这类球铁具有优良的综合机械性能、强度高、耐磨性好、韧性好、特别是有高的缺口韧性,可代替钢,用于制作重要受力结构件,如曲轴、齿轮、凸轮轴等。
