A Study of the Microstructural Evolution and Strengthening Effects of Non-Spherical Precipitates in an Al-Cu-Based Alloy

Abstract:

Article Preview

The microstructural evolution and associated strengthening during isothermal ageing of an Al-3Cu-0.05Sn reinforced by non-spherical θ' (Al2Cu) precipitates is studied. Emphasis is placed on the plate shape of the θ'. It is found that the microstructure parameters governing the magnitude of the precipitation strengthening effect are completely different from the classical case of spherical precipitates. New possibilities for microstructure design are discussed.
