| 英文摘要: |
| Laser Additive Manufacturing (LAM) is actually an advanced manufacturing technology that combines precision shaping with high-performance. Firstly, the forming principles and characteristics of two typical LAM technologies were intro-duced. Then the research progress in tissue regulation and anisotropy of high performance titanium alloy by LAM in Xi'an Jiaotong University was introduced emphatically: ① The influences of boron metamorphism on tissue regulation and anisotropy of LAM TC4 parts; ② The influences of silicon modification on TC4 microstructure of inductively heated assisted LAM; ③ The effects of ultrasonic impact forging on tissue regulation and anisotropy of LAM TC4 parts. Ultimately, the challenges and tasks that LAM technology may confront with were explained. |
