Effect of layer thickness and laser emission mode on the microstructure of an additive manufactured maraging steel

In this work, a high-performance maraging steel M300 was processed by laser powder bed fusion, where the layer thickness and the laser emission mode were modified. As-built microstructures were studied by considering the metallurgical phenomena taking place during printing: melting of the material d...
