Abstract Scope |
Due to outstanding properties copper (Cu) and Cu alloys represent one of the major groups of commercial metals with respect to production and consumption. However, the low strength of copper is referred to as the main drawback. CuCrZr represents a candidate to satisfy strength limitations by aging heat-treatments. Conventional manufacturing becomes extremely challenging when machining of complex components is required. Identification of processing routes, such as Laser-Based Powder Bed Fusion (PBF-LB), can be seen as a crucial step towards time and cost efficient production of CuCrZr.
The current study focusses on the influence of heat treatments on microstructure and mechanical properties, especially in the low-cycle-fatigue regime, of CuCrZr processed by PBF-LB. Results are discussed based on microstructural investigations (SEM and CT)and on fracture surface analysis, providing novel insights on the role of geometrical parameters to the process window allowing for robust and reliable establishment of solid structures. |
