Abstract
The effect of copper composition on the structure and mechanical properties of CuAlNi alloys was investigated using MD simulation and characterization methods. It was found that the structure of CuAlNi alloys markedly resembles Cu composition, which alterations from the initial single (FCC) to (BCC) structure and then to a duplex BCC structure as the Cu content is raised. Nanoindentation measurements show that the hardness of CuAlNi alloys increases with Cu content. When there are more Al elements, the surface of the material is first combined with ions in seawater so that the corrosion potential is significantly reduced. This research seeks to identify CuAlNi alloys with improved properties through molecular dynamics simulations and experimental analyses, highlighting the connections between microstructure and mechanical behavior.
期刊介绍：
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
