50B (930℃×1h oil quenching) metallographic diagram
The microhardness, composition and fraction and morphology of the as-quenched cobalt-containing iron-chromium-nickel alloys (930°C × 1h oil-quenched) were studied for the study of microstructure of the alloys. The cobalt-containing iron-chromium-nickel alloys were obtained from the vacuum arc me......

Low microstructure and non-metallic inclusions in 50Mn steel (hot rolled and slow cooled)
Abstract
This paper studies the low-magnification microstructure and non-metallic inclusions of 50Mn hot-rolled steel. Optical microscopy (OM) and scanning electronmicroscopy (SEM)were used to study the microstructure of 50Mnhot-rolled steel. The results showed that the microstructure was a mixtu......
