| Abstract Scope |
QuesTek Innovations LLC utilized its Integrated Computational Materials Engineering (ICME) tools and expertise to design and develop a next generation fully-austenitic TRIP steel aiming at high yield strength, high toughness, and good weldability. Using a systems-based approach focusing on process-structure-property relationships, a cost-effective fully-austenitic TRIP steel composition with optimized homogenization and annealing heat treatment cycle was designed. The designed steel was predicted to have high strength due to gamma-prime precipitation in the austenite matrix and improved toughness due to transformation induced plasticity (TRIP) effect along with achieving other key design criteria such as to avoid formation of detrimental secondary phases, good weldability, avoid excessive grain coarsening. Results from experimental prototyping of the designed steel, its microstructural characterization and mechanical property testing will be discussed. The calibration and validation of developed models to predict the microstructural features and mechanical properties using the experimental results will also be reviewed. |
