Název v původním jazyce

The real structure of γ-Fe phase of rolled 1.4470 duplex steel after shot peening

Popis výsledku v původním jazyce

Duplex stainless steels exhibit better properties, such as corrosion resistance, compared to single-phase steels. They are widely used in many engineering areas. Shot peening is commonly used technique in surface machining. It is used to further improve the final properties, such as service life. It is essential to know how this process affects the so-called real structure, which to great extend determines the final properties of the steel. The impact of shot peening intensity on crystallite size, residual stresses and preferred orientation was studied. It was found that shot peening caused a reduction in crystallite size in subsurface layers. It also led to an increase in compressive residual stresses in near-surface regions. The influence on preferred orientation was not as strong, yet some crystallites were rotated and reoriented.
