Effect of thermo-mechanical treatment on the static and cyclic performance of cold sprayed 6061 aluminum alloy
Original language description
This paper investigates the influence of hot-rolling as a post-deposition treatment on the microstructure and mechanical properties of cold sprayed Al-6061 deposits prepared using nitrogen as the process gas. Various degrees of hot-rolling, followed by solution-aging heat treatment, were applied to enhance inter-particular bonding and improve mechanical performance. The treatment significantly densified the deposits and induced changes in the grain structure through static and dynamic recrystallization. Microhardness measurements, static tensile tests, uniaxial fatigue tests, fatigue crack growth rate tests, and fracture toughness assessments demonstrated notable improvements in the material strength, fatigue resistance, and crack growth behavior. The proposed approach will be effective for fabricating large-scale components with simple geometries. Additionally, it serves as a means to explore the upper bounds of microstructural and mechanical performance achievable in nitrogen-based cold sprayed deposits through extensive thermo-mechanical processing.
