The invention discloses a forging method for improving the microstructure uniformity of TC18 titanium alloy bars. The method comprises the following steps: heating TC18 titanium alloy ingots, carrying out upsetting and rolling forging once, and pressing down the forged ingots in a downward pressing process to crush an original cast microstructure; and carrying out upsetting and rolling forging on the obtained forging stock at a temperature being greater than a beta phase transition point 2-3 times, carrying out upsetting and rolling forging on the obtained forging stock at a temperature being smaller than the beta phase transition point 2-4 times to prepare a 16-surface object, and carrying out precise forging on the 16-surface object at a temperature of Tbeta-50DEG C once to finally produce TC18 titanium alloy bars with the diameter of 160-260mm.
