To achieve the desired mechanical, chemical, and physical properties of components in thermal processes such as welding, casting, hardening, sintering, and laser melting, a thorough understanding of the diffusion, recrystallization, and phase transformation processes occurring within the materials is required. This is crucial for process control and, ultimately, the durability, strength, and resistance of components.
Examples of specific challenges we address in our projects:
- Temperature control in heat treatment
- Achieving desired microstructures
- Phase separation and diffusion processes in multiphase alloys
- Residual stress management and distortion control
- Porosity and density control during sintering
- Parameter tuning in selective laser melting
