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.

铜铝镍合金的机械和电化学特性分析

利用 MD 模拟和表征方法研究了铜成分对 CuAlNi 合金结构和机械性能的影响。研究发现，CuAlNi 合金的结构与铜成分有明显的相似性，随着铜含量的增加，其结构从最初的单一（FCC）结构转变为（BCC）结构，然后又转变为双相 BCC 结构。纳米压痕测量表明，CuAlNi 合金的硬度随 Cu 含量的增加而增加。当铝元素较多时，材料表面会首先与海水中的离子结合，从而大大降低腐蚀电位。这项研究旨在通过分子动力学模拟和实验分析，找出具有更好性能的 CuAlNi 合金，突出微观结构与机械行为之间的联系。

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.
