The purpose of this research proposal is to investigate the effect of accumulative back extrusion (ABE)on the material properties of AA 6061 aluminum alloy, which includes how working parameters affect theproperties of the material being investigated, how the correlation between microstructure and property of thematerial is, and how to evaluate the improvement on the material produced by ABE. To achieve the goal, inthe research proposal a set of non-commercialized accumulative back extrusion will be developed, with whicha number of experiments will be conducted on a 100-tons material testing machine. Experimental design willselect the deformation ratio as well as the die stroke as continuous working parameters, and both materialhardness and material homogeneity as response quality. In addition to these continuous parameters, theexperimental design will also take into consideration the extrusion path, a discrete working parameterconsisting of the orientation of specimen and the number of cycles applied in ABE test. The research proposalis of highly theoretical interest because that the extrusion path has not been found to be satisfactorily studied,so far, in the literature.The reason for AA 6061 aluminum alloy being selected to investigate is due to its lightweight, beneficialto lightweight structural design after improved. Also, the capacity in power of the existing material testingmachine is another key to choosing such a material for the assurance of successfully performingexperiments.
