Duplex and Superduplex Stainless Steels: Microstructure and Property Evolution by Surface Modification Processes

The paper presents an overview of diffusion surface treatments, especially nitriding processes, applied to duplex and superduplex stainless steels in the last five years. Research has been done mainly to investigate different nitriding processes in order to optimize parameters for the most appropria...
