We report the fabrication of the 304 stainless steel by the laser rapid prototyping harmonized with high-frequency micro-forging and demonstrate that both microstructure and properties of the prepared samples can be enhanced significantly. Structurally, we find that the large regular dendritic microstructure can be broken into pieces and that the internal defects are to some extent eliminated. Moreover, grains are refined remarkably. As a consequence of such structural modification, mechanical properties are found to be enhanced considerably by demonstrating a much broader fluctuation in tensi...
