WebbHowever hot forming of TiAl often takes place at temperatures and in phase fields with α-Ti (Al) as the main phase. For a long time little was known about the texture formation of α-Ti (Al) and its influence on the texture of γ-TiAl, to which it transforms at lower temperatures. WebbFigure 3. TNM billets after (a) upsetting to an overall strain of 0.7 and (b) after side pressing to an overall strain of 1.3. Photographs (c) and (d) show different TNM blade pre-forms manufactured by upsetting both sides of a cylindrical bar and subsequent side pressing to final shape (3-step forging process).
