Abstract Knowledge of the TTT (Time-Temperature-Transformation) or CCT (Continuous- Cooling-Transformation) diagrams of steels is an important factor in the thermo-mechanical processing of steels.Much experimental work has been undertaken to determine such diagrams.Cited by 16Publish Year 2004Author Sandra Rugonyi,Ethan C.Smith,Stephen B.HallGENERATION OF TTT AND CCT CURVES FOR CAST TIefforts have been made to generate the TTT and CCT curves for it,there is no published TTT or CCT curves that have been widely accepted.In this project,we aimed to generate the TTT and CCT curves for Ti-6Al-4V alloy based on the microstructures analysis of the isothermal treatments,Jominy end quench,and continuous cooling experiments.Continuous Cooling Transformation (CCT) of Austenite These diagrams are called continuous cooling transformation (CCT) diagrams actually a TTT diagram can be easily determined needing relatively simple experimental set up and metallographic equipment.For these reasons,though the usefulness of CCT diagram was realised quite long back,most of the early work on the transformation in steels has been done on determining the TTT diagrams.
