| Abstract Scope |
The present work focuses on manufacturing bulk nanocrystalline Al-Mg alloys using cryomilling and high-pressure cold spray (HPCS) techniques. The Al and 5 wt. % Mg powders were pre-mixed and cryomilled for 2, 4, 6, and 8 hours. The HPCS technique was utilized to deposit cryomilled powder onto the Al substrate. After deposition, the thick deposited layer was extracted from the Al substrate, resulting in a standalone component. The morphology and crystallite size of both cryomilled powder and HPCS components were studied using scanning electron microscopy, X-ray diffraction, and transmission electron microscopy. The results showed that the crystallite size of the powder was reduced with the increased cryomilling time and was retained in the component after HPCS deposition. In addition, HPCS components showed enhanced mechanical properties, compared to traditional Al alloys. The manufactured alloy component has the potential to be used in automotive, aerospace, and marine sectors for high-strength lightweight applications. |
