1) reversed austenite
回转奥氏体
1.
9Ni steel has the mechanism of excellent cryogenic toughness, first explanation is that reversed austenite prevents the cracks from spreading; second explanation is that reversed austenite produces deformation to induce martensite transformation, which prevents cracks from germinating and extending; Furthermore, third explanation is th.
9Ni钢具有良好低温韧度的机理,一种解释是回转奥氏体阻止裂纹的扩展即裂纹尖端钝化效应。
2.
The changes of amount,distribution and stability of reversed austenite and their effects on the cryogenic toughness of 9Ni steel treated by two-phase region heat treatment were studied with XRD and EBSD.
通过XRD测定了9Ni钢中的回转奥氏体含量,并采用EBSD技术观察其在基体上的分布,研究了两相区热处理后回转奥氏体含量、分布及其稳定性的变化以及这些因素对9Ni钢低温韧性的影响。
2) Austenitic stainless steel rotary belt
奥氏体不锈钢回转钢带
4) Reverted austenite
逆转奥氏体
1.
The absence of cementite and formation of reverted austenite at the plate boundaries tempered at 482℃ are the main factors.
2 3NiCo钢在 482℃回火组织中板条边界形成薄膜状的逆转奥氏体和不存在渗碳体是主要的组织因
2.
Although the steel tempered at 482℃ has higher strength,the formation of the reverted austenite film along the boundaries of lath martensite makes steel possess higher resistance of hydrogen embrittlement.
482℃回火,虽然强度较高,组织中存在的沿马氏体板条边界以薄膜状分布的逆转奥氏体,使钢在此温度回火具有较高的氢脆抗力。
6) austempering temperature
奥氏体回火温度
1.
According to the production of ADI,sample with three kinds of austempering temperature,namely 300 ℃,350 ℃,400 ℃ were prepared and their mechanical performance was tested.
结合现有ADI材料的生产情况,选取300、350、400℃3个奥氏体回火温度,制备3组试样并测定力学性能。
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。
