Microstructure Evolution Analysis
OpenPhase excels at simulating microstructure evolution by considering various physical effects. For example, simulating creep in Ni-base superalloys at 950°C and 350 MPa stress involves the interaction of interface kinetics, diffusion, plasticity, and elasticity.
Our approach is versatile and can be applied to different material systems and processes where phase transformation and/or plasticity are critical, including tensile tests and heat treatments.
Mechanical Properties Simulation
Mechanical properties are crucial for metallic materials, determined by grains, phases, precipitates, and defects within the microstructure. In nickel-base superalloys, the unique microstructure formed by gamma (γ) and gamma-prime (γ′) phases embedded in a gamma matrix evolves during creep deformation, resulting in exceptional creep resistance.
