OpenPhase Capabilities
OpenPhase is the premier software for providing solutions and deeper insights into deformation mechanisms. Our solutions include:
- Different heat treatments to produce varying sizes of γ′ precipitates.
- Calculation of local stresses based on misfit and external loads.
- Directional evolution of microstructure under elastic or elastic-plastic environments.
- Impact of alloying elements on microstructure evolution and creep properties.
- Non-homogeneous elastic and plastic deformation of superalloys.
- Effect of shear bands on microstructural evolution.
- Local crystal rotations during creep and plastic deformation.
- Rafting of microstructure leading to topological inversion.
Microstructure Evolution
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. This simulation provides detailed insights such as creep curves, phase fractions, and element distributions.
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
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.
OpenPhase integrates diffusion, phase transformation, elasticity, and plasticity modules to precisely simulate creep deformation at the microstructural level. This allows for detailed analysis of microstructural processes and their macroscopic effects, such as creep curves.
Our simulation approach is adaptable to various material systems and processes involving phase transformation and plasticity, including tensile tests and heat treatments.
