Abstract :
Despite the increased usage of composite
materials, high-strength aluminum alloys maintain
significance in airframe construction. Aluminum's
attributes of being lightweight, relatively low-cost, heat-
treatable, and capable of withstanding high-stress levels
contribute to its continued importance. These properties
also reduce manufacturing and maintenance costs
compared to other high-performance materials. Recent
advancements in aluminum aircraft alloys have enabled
them to compete effectively with modern composite
materials. This study delves into the latest developments,
focusing on improving the mechanical properties of
aluminum alloys and utilizing high-performance joining
techniques. Cu-Al-based alloys represent a new class of
functional materials. Due to their unique thermoelastic
martensite structure, their exceptional damping
performance has garnered attention in materials science
and engineering. However, challenges such as elastic
anisotropy and larger grain sizes can lead to brittle
fractures, impacting the material's mechanical properties.
It is widely acknowledged that achieving a finer grain size
is pivotal when creating Copper Aluminum alloys with
exceptional mechanical attributes and effective damping
characteristics. Smaller grain sizes allow for the combined
use of fine grain strengthening and interfacial damping,
resulting in alloys demonstrating exceptional overall
characteristics. This paper presents several standard
approaches for preparing Copper Aluminum alloys,
subsequently examining research efforts dedicated to
enhancing grain size through alloying and heat treatment.
Moreover, nanomaterials are being investigated as
potential agents for reinforcing Cu–Al-based alloys,
leading to substantial improvements in their mechanical
characteristics and damping capacities. The study aims to
serve as a valuable reference for future research in
developing structure-function integrated materials capable
of simultaneously offering high strength and high damping
characteristics.
