Abstract
Laser quenching is an effective method to improve the surface performance of steel and iron. However, temper softening in overlapping zone often exists in multi-track laser quenching process and results in non-uniform hardness and residual stress distribution in the surface of component. Here, QT-700-2 nodular cast iron (QT-700-2) was performed by laser quenching with the maximum power of 3000 W and subsequent dual shot peening. With optimized...
