abstract
The mechanical response and damage mechanisms of rolled Al 6061-T6 alloy subjected to tensile testing at different temperatures and various strain rates have been investigated in this paper. The evolution of the microstructure has been examined for the different testing conditions showing strain rate and temperature effects. The fracture surfaces of samples damaged at different uniaxial testing conditions were observed through Scanning Electron Microscope (SEM). Annealing tests at different temperatures have been performed and microstructure analyses for each condition have been achieved showing grain size evolution. Investigation of the fracture initiation sites has been achieved by conducting interrupted tests and observing the microstructure through SEM. Observations has pointed out that precipitates and iron rich phases are privilege cites for crack initiation.
