Evolution of microstructure and precipitates in 2xxx aluminum alloy after severe plastic deformation

Bogusława Adamczyk-Cieślak , Joanna Zdunek , Jarosław Mizera


This paper investigates the influence of precipitation on the microstructure development in a 2xxx aluminum alloy subjected to hydrostatic extrusion. A three step reduction of the diameter was performed using hydrostatic extrusion (HE) process: from 20mm (initial state) to 10 mm, 5 mm and 3 mm, which corresponds to the logarithmic deformations ϵ = 1.4, ϵ = 2.8 and ϵ = 3.8 respectively. The microstructure and precipitation analysis before and after deformation was performed using transmission electron microscope (TEM), and scanning electron microscopy (SEM). As a result of the tests, a very significant influence of precipitation on the degree of refinement and mechanism of microstructure transformation was stated.
