Summary: | The invention provides a processing method for raising strength and toughness of TC4-DT titanium alloy sheet materials. The method comprises the following steps: first, TC4-DT titanium alloy ingot castings are subjected to cogging forging to obtain first forging stocks; second, the first forging stocks are subjected to first upsetting forging to obtain second forging stocks; third, the second forging stocks are subjected to second upsetting forging to obtain third forging stocks; fourth, the third forging stocks are subjected to drawing forging to obtain fourth forging stocks; fifth, the fourth forging stocks are subjected to saw cutting blanking, heated, and subjected to plate slab pressing forging to obtain semi-finished product sheet materials with a thickness of 31mm-56mm; sixth, the semi-finished product sheet materials are subjected to heat treatment and machine processing treatment to obtain TC4-DT titanium alloy sheet materials with a thickness of 25mm-50mm. The processed TC4-DT titanium alloy sheet m |
