%X The formation reason and elimination method of non-uniform microstructure defects in Ti al-loy TC11 bar have been studied.The coagulating and coarsening into block of the part ofgrain boundary α and secondary α seem to be caused by the ingot cogging and initial forgingtemperature in the β region as well as no more enough deformation and uneven distribution.The grain α,elongated α and blocky α may be finally eliminated by adopting the technique of(α+β)thermomechanical processing+β processing,W.Q.+recrystallization annealing,A.C.,thus the size of uniform and fine equiaxed α structure is believed to be reduced to 1.9258μm.
