Claim 5:
6. The method according to claim 1, wherein the metastable β-type titanium alloy forgings is prepared by a method comprising the following steps:
mixing titanium alloy raw materials, smelting, casting and scalping to obtain titanium alloy ingots; and
subjecting the titanium alloy ingots to a cogging forging and an α/β phase region forging in sequence to obtain the metastable β-type titanium alloy forgings, wherein
the temperature of the cogging forging is 100-200° C. above the α/β transition temperature of the metastable β-type titanium alloy; and
the temperature of the α/β phase region forging is 20-100° C. below the α/β transition temperature.
