Paper Title:
Recrystallization during Beta Working of IMI834
  Abstract

The microstructure evolution of near-alpha IMI834 titanium alloy during hot working in the beta phase temperature regime has been investigated with regard to the effects of deformation and heat treatments. Typical cogging conditions were simulated through compression testing at temperatures of 1025°C-1100°C, strain rates of 0.01s-1-1s-1, and post- deformation heat treatments up to 4h. An analysis of flow behaviour and as-deformed microstructures revealed mechanisms of dynamic recovery and recrystallization in operation during deformation. However, complete grain refinement was not achieved through dynamic recrystallization and subsequent heat treatment was required for microstructure homogenization through metadynamic recrystallization and grain growth. The mechanisms of dynamic and metadynamic recrystallization are considered through quantitative measures of beta grain size and available literature models.
