Cold spraying is a promising approach for the processing of refractory metals. A powder material is accelerated and heated in the gas flow of a supersonic nozzle to velocities that are sufficient to obtain cohesion of the particles to a substrate due

Selective Laser Melting (SLM) offers great potential for the processing of molybdenum as it allows the production of parts that can hardly be fabricated in a classical way. The workpiece is built up by melting up powder layer by layer. Besides the ap

Molybdenum, processed by laser powder-bed fusion (LPBF), is susceptible to hot cracking because segregated oxygen impurities significantly weaken grain boundaries through the formation of MoO2. The present study reports on the LPBF processing of the

Carbon is known to improve the ductility and grain boundary strength of molybdenum. Scientific consensus to explain this phenomenon is that carbon either replaces oxygen impurities at grain boundaries or suppresses the diffusion of oxygen towards the
