TA10 titanium plate for nuclear reactor creep

When TA10 titanium alloy is used in the creep environment of a nuclear reactor, its composition design must strictly control the palladium (Pd) content to 0.20%-0.30%, the iron (Fe) content to ≤0.30%, and limit the content of impurity elements such as oxygen (O) to ensure high-temperature stability. In terms of mechanical properties, the tensile strength at room temperature should be ≥620 MPa, the yield strength ≥550 MPa, and the elongation ≥18%, while also meeting the high-temperature creep strength requirement, reflecting its fracture resistance.

Regarding creep characteristics, TA10 titanium plates need to be processed using a two-stage cold rolling process (e.g., intermediate annealing temperature 640-680℃) to control the grain size to grade 5-7, balancing high-temperature plastic deformation and resistance to brittle fracture. The ratio of its creep strength to its endurance strength must be maintained at a high level to ensure long-term service safety.‌
