1)  austenite film
奥氏体薄膜
1.
The results show that the experiment steel maintains excellent impact toughness at low temperature during second welding thermal cycle because of the exist of austenite film between lath martensites.
采用焊接热模拟试验及金相、透射电镜分析技术研究了10Ni8CrMoV钢一次热循环的粗晶区在二次热循环过程中的组织转变与韧性特征,结果表明:由于马氏体板条间奥氏体薄膜的存在,10Ni8CrMoV钢在二次热循环作用下仍具有良好的低温冲击韧度,再热粗晶区、临界再热粗晶区均未出现局部脆化现象。
2.
The results of simulated experiment and actual weldment indicate that at appropriate accelerating cooling rate the M-A constituent in HAZ is reduced obviously in amount and replaced by tough austenite films.
热模拟及实际焊接接头实验结果表明:适当提高冷速后,热影响区贝氏体基体中高碳高硬度的M-A组元明显减少,并被韧性 的残余奥氏体薄膜所取代;而在喷水冷却的高冷速下得到了粗大贝氏体束组织,韧性反而没有改善。
3.
The results show that the tested steel maintains excellent impact toughness at low temperature during second welding thermal cycle at peak temperature 900℃ because of the existence of austenite film between lath martensites.
结果表明:由于马氏体板条间的稳定的奥氏体薄膜的存在,该钢一次热循环粗晶区在经峰值温度为900℃二次热循环作用后仍具有良好的低温冲击韧度,临界再热粗晶区未出现局部脆化现象。
2)  austenitic layer with higher carbon
富碳奥氏体薄层
1.
It was discovered that there is a austenitic layer with higher carbon around proeutectoid ferrite and that the distribution of carbon in the austenitic layer is not all continuous and homogene.
发现先共析铁素体周围存在有富碳奥氏体薄层 ,且此富碳奥氏体薄层中的碳分布并非都是连续的 ;此一富碳奥氏体薄层的特征与随后转变所形成的珠光体及马氏体形态相关。
3)  film of retained austenite
残余奥氏体膜
4)  Austenitic stainless steel extra-light wall tube
特薄壁奥氏体不锈钢管
5)  granulationes arachnoideales
帕基奥尼氏体;蛛网膜粒
6)  austenitic [英][,ɔ:stə'nitik]  [美][,ɔstə'nɪtɪk]
奥氏体
1.

冲压用冷轧奥氏体不锈钢带的表面质量控制
2.
Supersonic detection for welding joint of austenitic stainless steel small-diameter pipe;
奥氏体不锈钢小径管焊缝超声波检测
3.
Inspection detection research in austenitic stainless steel with different ultrasonic probes;
奥氏体不锈钢焊接接头超声波检测研究
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。
