| Abstract Scope |
Aluminum-based metal matrix composites with ceramic reinforcements offer high strength, stiffness, and wear resistance. However, conventional additive manufacturing methods face challenges with particle clustering. To overcome this challenge, a new hybrid additive manufacturing process was developed, combining cold spray and multi-track friction stir processing. This innovative approach successfully produced a fully consolidated composite material by eliminating cold spray deposition porosity through friction stir processing. The resulting material was analysed using various techniques, including optical microscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray microcomputed tomography. Microhardness measurements and Charpy impact tests were conducted to evaluate the mechanical properties of the hybrid material. The influence of this novel hybrid process was assessed, and predictions were made regarding the mechanisms associated with the evolution of the microstructure and the enhancement of mechanical properties. |
