Abstract Scope |
Additive manufacturing is an attractive technology for refractory metals due to the possibility of producing elements in any shape with low waste amount. That gives them an advantage compared to classical methods of production especially in the case of critical materials. Due to their properties it is difficult to obtain prints with optimal density and quality. Printability problems are investigated by development of processing parameters and modification of feedstock powders. We propose rhenium for modification, which is an important alloying element for tungsten and molybdenum. It increases the ductility at low temperatures, high temperature strength and plasticity, stabilizes the grain structure, improves the weldability and decreases ductile-to-brittle transition temperature. Different processes were used in order to obtain sphericity powders, characterized by good flowability, density and chemical homogeneity. W-Re and Mo-Re prints were made using the LPBF method. The influence of different parameters and rhenium addition on samples properties was investigated. |
