| 摘要 |
The invention relates to a monolithic titanium alloy (M) comprising, in a temperature range (DeltaT) and at atmospheric pressure: an outer peripheral zone consisting of a micro-structure (m1) having a modulus of elasticity (E1) and possessing superelastic properties in said range (DeltaT), and a core consisting of a microstructure (m2) having a modulus of elasticity (E2), and possessing elastic properties in said range (DeltaT); said microstructures (m1) and (m2) being different from one another, and said modulus of elasticity (E1) being lower than said modulus of elasticity (E2). |
