Overview
Nanocrystalline Alloys and Grain Boundary Engineering
Nanocrystalline alloys exhibit a wide range of both mechanical and functional properties that often exceed what is achievable at the microscale. However, they are often in unstable, nonequilibrium states due to a high concentration of grain boundaries that contribute to a large driving force for grain growth at the nanoscale.
Microparticle Impact
A wide range of interesting phenomena can occur when metallic particles impact metal surfaces at supersonic speeds, including adhesion, melting, cratering, erosion, and hydrodynamic shock-induced jetting. The Schuh group is systematically investigating high-speed microparticle impacts using a new real-time observation method that allows for direct nanosecond scale observation of the moment of impact, as well as finite-element modelling.
Shape Memory Materials
As a new emerging class of shape memory materials, shape memory ceramics offer unique properties that may not be achievable with their metallic counterparts; higher martensitic transformation temperatures with excellent oxidation resistance, higher transformation stresses, and higher work outputs than all currently existing actuators.
