Abstract:

BT-14 titanium alloy plate is the structure material of some hatch product. By the inspection before welding, the titanium alloy surface presences some white spots. The white spots surface pattern, microstructure as well as mechanical property were analyzed. The influence of the white spots organization on titanium plate us. ability was studies with emphasis, and precaution in the production follow-up was put forword.
