Tribological and Mechanical Characterization of Nickel Aluminium Bronze (NAB) Manufactured by Laser Powder-Bed Fusion (L-PBF)

To cope with the increasing demands of high-performance materials, efforts were made using Laser Powder Bed Fusion technique (L-PBF), taking advantage of its extremely short solidification time to fabricate copper alloy with highly refined microstructure. Copper and Copper alloys are reputed for the...
