Abstract:  
Bainitic-austenitic nodular cast iron, which is produced by austenitizing and incomplete isothermal transformation, shows high tensile strength combined with remarkable ductility. In the present paper, the consequences of shot peening on the surface and subsurface material states and on the bending fatigue behaviour are investigated. Pearlitic nodular cast iron was austempered in a salt bath at 300+
