Mechanical and thermal performance of additively manufactured copper, silver and copper–silver alloys

On-demand additive manufacturing (three-dimensional printing) offers great potential for the development of functional materials next generation energy-efficient devices. In particular, novel suitable efficient dissipation localised heat fluxes and non-uniform thermal loads with superior mechanical performance are critical accelerated future automotive, aerospace renewable energy technologies. this regard, study reports laser powder bed fusion processing high purity (>99%) copper (Cu), silver (Ag) copper–silver (CuAg) alloys ready on-demand manufacturing. The processed were experimentally analysed their relative density, using X-ray computed tomography, destructive tensile testing flash apparatus, respectively. It was found that while Ag featured higher failure strains, Cu in comparison showed a 109%, 17% 59% improvement yield strength ([Formula: see text]), Young’s modulus ( E) ultimate strength, As such [Formula: text], E is comparable to commercially available materials. CuAg alloys, however, significantly outperformed Ag, all commercial when it came offering performance. composition 105%, 33% 94% Cu. Although slightly different, trend continued 106% 91% rise text] respectively, industry-standard Unfortunately, values not available. When performance, offer 70% diffusivity despite variation density porosity. however only 0.8% 10–30% increase Ag. Overall, presents new understanding regarding three-dimensional printing Cu, alloys.
