淬火马氏体
1.
The white layer is practically nanocrystalline quenched martensite with great lattice distortion and internal stress.
白亮层的本质是纳米晶淬火马氏体,晶格畸变大,内应力大;另一方面,模具几何尺寸如尖角效应,也产生局部应力集中。
2.
It has been found that the reasor of early fracture of sheller is that the retained austenite was transformed into the quenched martensite and strain induced martensite during the service.
结果表明,造成退壳器早期断裂失效的原因是,零件在低温(-60℃)和循环载荷作用下,在使用期间部分残余奥氏体转变为淬火马氏体及应变诱发马氏体,从而在构件内部产生大量的应力集中源,疲劳裂纹首先萌发于此处,然后快速扩展直至断裂。

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。
