Combining maximal strength and deformability serves as guidance for the development of future metallic materials. However, the realization is very challenging because strength and ductility/toughness are conflicting properties. This is our motivation to develop metallic thin film composites with optimized strength and deformability.
We develop pulsed metallurgy as a microstructure design tool enabling us to control and link the thin film microstructure to its properties and performance. In greater detail, we strive to the control of phases, their fraction, and their morphology at the nanoscale paving the way to the development of novel nano-composites with tailored mechanical properties.
Pulsed metallurgy utilizes effects of thermal pulsing on metallurgical processes at the nanoscale, such as interdiffusion and phase nucleation and growth. Together with our collaborators, we fabricate the thin films and characterize and model the metallurgical transformations for pre-defined thermal histories and explore:
