Investigation of defects and stresses in SiFe steel surfaces

SiFe specimens prepared from GO steel with different surface treatments were studied from the point of view of structure, stresses and defect density using the conversion electron Mössbauer spectroscopy (CEMS) and the slow positron annihilation spectroscopy (SPAS). Amounts of the high defect density...

Zusammenfassung:SiFe specimens prepared from GO steel with different surface treatments were studied from the point of view of structure, stresses and defect density using the conversion electron Mössbauer spectroscopy (CEMS) and the slow positron annihilation spectroscopy (SPAS). Amounts of the high defect density (HDD) phase and defect depth profiles were obtained for specimens after mechanical and/or chemical surface polishing.
