Microstructure and Compressive behaviour of Thixocast 2014 Alloy: Effect of processing temperature
Keywords:
Microstructure, temperatureAbstract
In the present work, microstructure and mechanical properties of thixocast 2014 alloy were correlated and compared with gravity cast 2014 alloy having the same composition. Thixocasting of samples was done at 600°C, 615°C & 630°C within a cylindrical die. Microstructures and mechanical properties were observed, correlated and compared with those of gravity cast samples. The compressive strength, hardness and strain of the thixocast samples found to be higher than those of gravity cast samples. Improved mechanical properties of thixocast samples are due to non-dendritic globular structure and morphology of silicon particles.
