Technology Analysis and Optimization for Electric Hot Incremental Forming of Ti-6AI-4V Sheet |
|
| Abstract: | In the current work, electric hot incremental forming of Ti-6A1-4V titanium sheet is simulated by using MSC. Marc software. Processing parameters, such as feed rate, step down and current, are studied to find influences on force of toot, strain and temperature of Ti-6Al-4V sheet. Forming experiments are designed to verify the analysis. Results show that the current is the most important factor, and the best forming temperature range is 500～600 ℃. After processing, the ultimate strength of TC4sheet is reduced by 10%, and the hardness is increased by 14%. The research provides an instruction for the application of the technology. |
