Microstructure changes in a 2618 aluminium alloy during ageing and creep

Abstract

Microstructure changes and precipitation processes in the 2618 aluminium alloy were investigated. Denuded precipitation-free zones exist along grain boundaries due to reduced concentration of alloying elements (Cu and Mg).

These zones have a detrimental effect on mechanical properties of the alloy.
