Effects of rolling variables - strain (?), strain rate (?) and temperature (T) - on grain structure and hardness evolution in AA6061 plates were investigated by simulating the rolling process using plane strain compression (PSG). Particular emphasis was exerted on understanding the impact of the variables on the overall mean grain size and hardness, as well as how they influence the grain size and hardness profiles through the thickness of the rolled plates. Prior to PSG investigations, the grain size and hardness profiles of the supplied material (transfer and finished plates) were determined using a Reichert MeF3A optical microscope and Vickers hardness tester. No significant grain size variations were observed through the thickness of transfer plate. On the contrary, finished plates exhibited grain size gradients, with grain size progressively decreasing from the surface to the centre of the plate thickness. 2014-12-30T19:47:06Z 2014-12-30T19:47:06Z 2003 Master Thesis Masters MSc http://hdl.handle.net/11427/10615 eng application/pdf Department of Mechanical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
