Abstract:
Powder bed fusion of metals using laser beam (PBF-LB/M) creates a new platform for the fabrication of complex geometries from high-performance materials. In this regard, the high strength and thermal conductivity of CuCr1Zr lead to great interest in the aerospace and nuclear industries. By understanding the influence of powder properties, the quality of those critical components can be optimized. In this context, the present work investigates the effects of powder properties in PBF-LB/M of CuCr1Zr. For this reason, powders from different suppliers were characterized and processed. Subsequently, the achieved component density, hardness, and electrical conductivity were systematically investigated and discussed to define basic property profiles depending on the powder material.
