EBSD study of advanced Ti-5.7Al-3.8Mo-1.2Zr-1.3Sn alloy subjected to equal-channel angular pressing

• The lamellar component of the alloy was spheroidized after ECAP deformation. • The lamellar component was spheroidized by the boundary-splitting mechanism. • The evolution of the primary alpha phase is controlled by continuous recrystallization. • Burgers orientation relationship between the spheroidized α and β phases was found. In this work, electron backscatter diffraction (EBSD) was applied for microstructural characterization of the...
