Electroshocking treatment (EST) was a method to optimize the microstructure of titanium alloy. Under EST, the dense basket-weave structure in Ti-6.5Al-3.5Mo-1.5Zr-0.3Si (TC11) manufactured by laser melting deposition became sparse, and colony tissue nucleation grows near grain boundaries. The phase transformation induced by EST results in changes in the intensity and orientation of α and β textures in TC11, but α/β still obeyed the Burger orientation relationship, and the β phase content increased. At the same time, EST also promoted the dislocation movement near the grain boundary, and a mass of dislocation accumulation at the grain boundary increased the KAM value at the grain boundary.
