Laser surface melting has been widely used as a rapid screening technique for the evaluation of potential new rapidly solidified alloy compositions. The present study is an examination of the metallurgical and mechanical properties of nitrided EN-40-B steel surfaces subjected to Nd-YAG laser melting. It was found that mixing of the surface layer with the underlying material occurs at a depth of 0.25 mm below the surface and the hardness of the laser-melted zone varies considerably when compared with the nitrided zone.
