The ductile transfer temperature (DBTT) of modified tungsten materials can be evaluated by several test methods, such as tensile testing, bending testing, Charpy impact testing and fracture toughness testing. The DBTT is highly dependent on the test method, strain rate and specimen shape. Researchers have used Charpy impact and tensile tests to evaluate DBTT.

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.
