TīmeklisHerein, the surface decarburization and oxidation characteristics of Cr–Mo cold heading steel are investigated via optical microscopy, scanning electron microscopy, and electron backscatter diffraction under different temperatures. Furthermore, the competitive mechanisms of decarburization and oxidation are analyzed. The results … Tīmeklis2024. gada 29. apr. · The fracture was cut from the failed 55SiCr spring steel and cleaned by ultrasonic agitation in acetone. The surface of the sample was observed under a Zeiss stereo microscope. Then the fracture morphology was observed by FEI QUANTA FEG450 scanning electron microscope (SEM). Chemical Composition
