Laser Surface Remelting of AISI 4140 Steel
IOP Conference Series: Materials Science and Engineering, 2020 Abstract In order to improve the surface wear resistance and hardness, laser remelting was used to process AISI 4140 steel. The microstructure and the Vickers hardness of surface and cross-section of those samples were studied. The results shown the laser power was one of the most important facts, which affect the enhanced hardness and ...
