Microstructure and properties of AlCoCrFeNiNbx (x = 0, 0.1 and 0.5) high-entropy alloys enhanced by laser remelting

Effect of laser remelting power on the microstructure and properties of vanadizing layer on AISI 52100 steel pin shaft

“…The crystal grains gradually decrease from the sample to the heat-affected zone to the remelting zone. With the increase of laser power, the area of the remelting zone on the surface of the sample gradually increases, and more fine martensite is obtained to gradually increase the hardness [ 21 , 22 ]. It can be seen from the figure that with the increase of laser remelting power, the microhardness gradually increases.…”
