Superplasticity is generally achieved in titanium alloys with a fine grained microstructure when deformation is carried out under narrow ranges of strain rates and temperature. Under these conditions, titanium alloys show large elongations (i.e. optimal superplasticity) with a relatively stable microstructure. In superplastic deformation (SPD) process, strain-rate sensitivity exponent (m) is a critical parameter, which value quantifies the optimal superplasticity. In real industrial applications, maintaining these narrow ranges of condition required for optimal superplastic flow from beginning to end is a very difficult and challenging task. When the aforesaid conditions lie beyond a certain limit (i.e. at near...
