Laboratory of Advanced Manufacturing of Materials (LAMM) is focused on developing fundamental processing-structure-property relationships in materials for extreme environments and energy applications. The primary interest is to uncover the microstructural phenomena occurring at different lengths and time scales through sophisticated measurements and understand how those mechanisms can be utilized to dictate material design and performance.
- Spark plasma sintering (SPS) of structural and functional ceramics.
- High-strain rate (dynamic) deformation of advanced materials.
- Micro-mechanisms of deformation and failure in extreme environments.
- Microstructural characterization and structure-property relationships.
- Time-resolved diffraction measurements of lead-free piezoelectric ceramics.
- Advanced nanoceramics and composites for high-temperature aerospace components, impact protection and lightweight structures.
- Lightweight cellular solids for automotive bumpers, personal protective gears, kinetic energy absorption and shockwave mitigation.
- Dielectric, piezoelectric and ferroelectric materials for actuators, capacitors, sensors, sonar, ultrasounds, and energy harvesting.
- Material processing facilities
- Split-Hopkinson pressure bar (SHPB)
- Dynamic indentation hardness tester (DIHT)
