An investigation on microstructure evolution and deformation mechanism of Ti–5Al–5Mo–5V–1Cr–1Fe alloy during in-situ tensile
Source abstract
Abstract
The effect of volume fractions of α phase and β phase on the microstructure evolution and deformation mechanism of as-forged Ti–5Al–5Mo–5V–1Cr–1Fe alloy during in-situ tensile was investigated. The morphologies, low angle grain boundaries (LAGBs), textures, geometrically necessary dislocation (GND) densities and Schmid factors (SFs) of α phase and β phase during deformation were analyzed. The results showed that the volume fractions of β phase decreased from 42.7% to 28.8% while those of α phase increased from 57.3% to 71.2% when the stresses reached the critical induced stress. The microstructure evolution of α phase is more obvious than that of β phase with the variation about volume fractions of α phase and β phase. Besides, the number of LAGBs in α phase was increased with the increasing of volume fractions of α phase. The texture intensities of α phase were decreased with the increasing of volume fractions of α phase and those of β phase were increased with the decreasing of volume fractions of β phase. The effect of volume fractions of α phase and β phase on dislocation density and deformation mechanism was unobvious.
