| 英文摘要: |
| Titanium alloy has advantages of low density, high strength, good corrosion resistance, etc. However, the cold working performance of titanium alloy is low, and ultrasonic vibration assisted plastic forming technology can reduce the forming force and friction, improve the surface quality of parts and the material formability. In this paper, the technical principles, forming mechanisms and the applications of ultrasonic vibration assisted forming technologies were summarized briefly. The plastic forming characteristics of titanium alloy and the research status of ultrasonic vibration assisted plastic forming technology used for titanium alloy were introduced. The problems of titanium alloy ultrasonic forming technology were summarized. The work in literature shows that the ultrasonic forming technology of titanium alloy has very wide application prospect. It is the advanced and challenging research focus in the domain of titanium alloy forming technology. |
