Abstract

The invention discloses a high-damping single-phase alpha titanium alloy based on the martensite inner interface and dislocation mechanism. Components of the alloy comprise, by weight percentage, 1.0-1.5 wt.% of Si, 0.5-0.8 wt.% of Sb, 3.0-4.0 wt.% of Mg, 2.5-2.8 wt.% of Sn, 1.0-1.8 wt.% of Ta, 0.2-0.4 wt.% of Mo, 1.5-2.0 wt.% of V, 0.02-0.04 wt.% of C and the balance titanium. According to the material, a material science solution scheme different from a traditional titanium alloy is provided for damping occasions needing light weight, and the technical problem faced by the field at present can be effectively solved. Avoiding material fatigue damage becomes possible through vibration reducing, and great social benefits and economic benefits can be obtained at the same time.

Description

Technical field [0001] The invention relates to the technical field of alloys, in particular to a titanium alloy. Background technique [0002] Noise pollution caused by industrial vibration and noise has become a major hazard to humans, and together with water pollution and air pollution, it is regarded as the three major environmental problems worldwide. There are many sources of vibration and noise. The most important types are: (1) Abnormal vibration and noise caused by the rotation of the machine itself or part of the parts due to assembly loss and bearing defects; (2) When the object is impacted in a short time A large amount of kinetic energy is converted into vibration and noise; (3) resonance caused by the coincidence of the natural frequency of the object with the frequency of the external vibration; (4) the turbulence generated by the high-speed fluid encountering obstacles will cause vibration and noise. [0003] Vibration in the mechanical structure can cause severe b...
