Embodiment 1
[0011] In this embodiment, sponge titanium, electrolytic nickel, oxygen-free copper, metal zirconium and a small amount of rare earth yttrium (Y) are used to press into an electrode according to the design composition, and the electrode is smelted into a multi-element alloy high damping titanium with a conventional vacuum induction melting furnace alloy. The composition of the high damping titanium alloy is Ni: 25%, Cu: 25%, Zr: 1%, Y: 0.1%, and the balance is Ti and unavoidable impurities. After the alloy is smelted, a single casting or a combination of single casting and wire cutting is used to obtain the shock absorbing parts of the required size and specification. The damping performance is: tanΦ=0.21; the compressive yield strength at room temperature σ s =2510 MPa.
Embodiment 2
[0013] In this embodiment, sponge titanium, electrolytic nickel, oxygen-free copper, metal zirconium and a small amount of rare earth yttrium are pressed into electrodes according to the design composition, and the electrodes are smelted into a multi-element high-damping titanium alloy by conventional vacuum induction melting furnace. The composition of the high damping titanium alloy is Ni: 25%, Cu: 25%, Zr: 2%, Y: 0.1%, and the balance is Ti and unavoidable impurities. After the alloy is smelted, a single casting or a combination of single casting and wire cutting is used to obtain the shock absorbing parts of the required size and specification. The damping performance is: tanΦ=0.24; the compressive yield strength at room temperature σ s =2810MPa.
Embodiment 3
[0015] In this embodiment, sponge titanium, electrolytic nickel, oxygen-free copper, metal zirconium and a small amount of rare earth yttrium are pressed into electrodes according to the design composition, and the electrodes are smelted into a multi-element high-damping titanium alloy by conventional vacuum induction melting furnace. The composition of the high damping titanium alloy is Ni: 25%, Cu: 25%, Zr: 4%, Y: 0.1%, and the balance is Ti and unavoidable impurities. After the alloy is smelted, a single casting or a combination of single casting and wire cutting is used to obtain the shock absorbing parts of the required size and specification. The damping performance is: tanΦ=0.19; the compressive yield strength at room temperature σ s =2320MPa.
