Modified Tungsten Materials Inhibit Recrystallization

Annealing temperature dependences of Vickers hardness of pure W and modified tungsten materials image

An increase in deformation ratio of modified tungsten materials can produce relatively rapid microstructural recovery and is generally less resistant to recrystallization. In the present study, materials with higher deformation ratios showed slightly lower recrystallization temperatures compared to materials with lower deformation ratios having the same major chemical composition.
