Abstract
A method for forming a component from a Ti-alloy or Ni-alloy sheet material. The method comprising heat treating the
sheet material, wherein a final temperature of the sheet material is above 100°C below a b-transus temperature of the sheet material.
The sheet material is formed into a predefined configuration between two dies. Forming is completed before the temperature of the o sheet material reaches a start temperature for b to martensite transformation within the sheet material and wherein the temperature of
the dies is less than a finish temperature for b to martensite transformation within the sheet material.
