Selection and Design Principles of Wrought Aluminium Alloys for Structural Applications

摘要

This article discusses the fundamental principles associated with the selection of aluminium alloys for specific purposes, alloy design & heat treatment procedures and development of key microstructures responsible for obtaining desired properties in selected wrought Al alloys for aerospace and defence applications. Influence of micro/trace additions of suitable alloying elements on the microstructure and properties of high strength 7xxx series Al alloys is further highlighted.
