The coagulating and coarsening into block of the part of grain boundary α and secondary α seem to be caused by the ingot cogging and initial forging temperature 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.
