Temperature changes and loads during hot-die forging of a gamma titanium–aluminide alloy

Analysis Of Deformation And Microstructural Evolution In The Hot Forgingof The Ti-6Al-4V Alloy

“…Instead, the dynamic recrystallization is computed in the step that follows immediately after the deformation stops. The critical strain is usually a fraction of the strain at which the flow stress reaches its maximum: (6) where denotes the strain corresponding to the flow stress maximum. The value of is determined experimentally and is usually a function of strain rate, temperature, and initial grain size:…”

“…the effect of temperature on the properties and structure of the material being deformed [6,7]. Hence, by controlling the thermomechanical state of the deformation zone in the forging process it will be possible to substantially influence the mechanical and service properties of the products [8].…”

Hydrogen‐Induced Improvement of the Cylindrical Drawing Properties of a Ti–22Al–25Nb Alloy

“…In addition, an intricate multi-pass forming process is required. [1,17] Increasing the intrinsic plastic deformation, ability of Ti 2 AlNb-based alloys can fundamentally improve their processing properties and reduce difficulties in processing Ti 2 AlNb-based alloy parts. First, very few die materials can maintain their strength above 1 000 C without oxidization or with a very low oxidization rate.…”
