| Abstract Scope |
Ti407 is a newly developed Titanium alloy with low Al content. This work aims to investigate the deformation mechanism of Ti407 sheets under tensile along various sample orientations. To that end, in-situ tensile loading in an SEM was conducted on Ti407-sheet along with various directions to rolling direction (RD). Also, the microstructure evolution of the sample after different levels of deformation was measured using EBSD. The results indicate that the mechanical properties of this alloy are highly anisotropic and the deformation mechanism depends on the loading direction to RD. Microstructure analysis indicated that the initial material contains macro-zones parallel with the rolling plane. Results suggested that the dominant deformation mechanism in the 0RD sample is slip systems whereas a significant number of {11-22}<-1-123> twins have been developed in the 90RD sample to accommodate plastic deformation. The nucleation of twining was taken place at a strain of 0.08, within the micro-zones. |
