Innovative process breaks the cost barrier Costly and time-consuming high-temperature forming methods have limited the use of Ti-6Al-4V to highly stressed components in narrowly specialized and small volume applications. A new forming technology, High Pressure Warm Forming process (HPWF) combines high pressure with a moderately elevated temperature for a more rapid and cost-effective forming of aerospace-grade titanium parts. Combining moderate temperature with high pressure forming A moderate temperature elevation to approximately 270°C (520°F), combined with a high-pressure forming step at 140 MPa (20,000 psi) has proven to form Ti-6AI-4V sheet parts with high accuracy and excellent forming repeatability. The research indicates a possibility to significantly reduce the temperature from levels required in current hot-forming processes, i.e. ~700°C / 1,300°F.
