@article { , title = {Microstructure and mechanical properties of friction stir welded AA6092/SiC metal matrix composite}, abstract = {There is a need for improved understanding on the effects of friction stir welding (FSW) on the metallurgical and mechanical properties of aluminium matrix composite (AMC). In this study, AA6092/SiC/17.5p-T6 AMC joints were produced by using FSW with varying tool rotation and traverse speeds. The microstructural characterisation by scanning electron microscopy equipped with electron backscattered diffraction (EBSD) system revealed a substantial grain refinement and a homogeneous distribution of reinforcement particles in the nugget zone. The grain size of the nugget zone was greatly influenced by weld pitch, as a key indicator to control the amount of heat input, exposure time and cooling rate. Vickers microhardness profile across the welding zone revealed a significant difference in microhardness among the base metals, heat affected zone, thermo-mechanically affected zone and nugget zone. The tensile strength of the cross-weld specimens showed a high joint efficiency of about 75\% of the base metal combined with relatively high ductility. Low-cycle fatigue properties were investigated in the axial total strain-amplitude control mode (from 0.3\% to 0.5\%) with }, doi = {10.1016/j.msea.2018.10.116}, issn = {0921-5093}, journal = {Materials Science and Engineering: A}, note = {OA (CCBY) KJB 08.11.2018}, pages = {78-88}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://nottingham-repository.worktribe.com/output/1235712}, volume = {742}, year = {2019}, author = {Salih, Omar S. and Ou, Hengan and Wei, Xingguo and Sun, W.} }
