| Abstract Scope |
This study explores the effect of process parameters on the shape and microstructural characteristics of single tracks and layers of bimetal printing using Laser Powder Bed Fusion (L-PBF). For this purpose two different configurations of single tracks and single layers of maraging steel (M300) and copper alloy (C18150) bimetal were printed using, laser scan speed of 500 mm/sec to 1100 mm/sec and power ranging from 300 W to 550 W. The effect of these process parameters on laser single tracks was analysed quantitatively by measuring width, depth and height of melt pool. It is found that both melt pool width and depth decrease with the increase of laser scan speed. In addition, microstructural analysis reveals turbulence at the interface and traces of marangoni flow were also observed at the interface. The results could contribute to build parts with minimum defect formation resulting in improving mechanical properties of L-PBF printed parts. |
