Summary, Etc.  

요약Enhancing the mechanical and corrosion properties of aluminum is in demand due to its lightweight and exceptional physical properties such as high strength-to-weight ratio. However, commercial aluminum alloys are developed with focus on enhancing the mechanical properties than corrosion performance. Precipitation hardening has been used as primary strengthening mechanisms, which leads to deterioration in corrosion performance due to micro-galvanic interaction between matric and precipitates. Therefore, researchers are moving towards non-conventional techniques to mitigate this limitation. High energy ball milling technique is reported to enhance the mechanical and corrosion performance to produce high strength and high corrosion-resistant aluminum alloys. The corrosion-resistant properties and high strength are attributed to the grain refinement and supersaturated solid solution. These promising alloys have also shown improved elastic modulus than commercial Al alloys by reducing the lattice parameter due to the accommodation of alloying elements. This work provides a significant contribution in unraveling the role of vanadium as an alloying element in inhibiting the corrosion and providing an additional barrier to the surface. The investigation has been conducted using advanced characterization techniques involving transmission electron microscopy and surface sensitive techniques such as X-ray photoelectron spectroscopy and secondary ion mass spectrometry. The use of these tools has expanded the understanding at nano regime and aided to present the corrosion mechanisms in nanocrystalline Al-V alloys obtained using high energy ball milling.
