对低碳马氏体型超高强良钢25SiMnCrNiMoV在不同工艺条件下的组织结构交化规律进行了仔细观察。透射电镜研究表明此钢淬火态具有自回火ε相,组织此位错马氏为主,板条间有时可能具有挛晶关系;部分残留奥氏体膜与两邻接的位错马氏体间可分别遵循K-S及N-W
The microstructure regularity of low carbon martensite super high strength steel 25SiMnCrNiMoV under different technological conditions was carefully observed. Transmission electron microscopy studies show that the quenched steel has a self-tempering ε phase, the organization of the dislocation of the Markovsky, lath sometimes may have a relationship between the twin; part of the residual austenite film and two adjacent dislocation martensite Can follow KS and NW respectively
