Abstract
The modified-constrained studded pressing (Modified-CSP) technique for improvement of the magnetic and microstructure properties of ultrafine-grain low-carbon steel sheets was investigated. The optical micrograph (OM) and scanning electron microscopy (SEM) showed that the microstructure of the samples was refined. Residual stresses and grain size of sheet samples were also investigated using X-ray diffraction (XRD) patterns. The residual stresses were increased sharply, and compressive residual stress was considered in the final pass. The vibration sample magnetometer (VSM) method was used to evaluate the magnetic properties. It was observed that the Modified-CSP method can produce low-carbon steel with ultra-fine grain and softer ferromagnetic properties.
