Abstract Scope |
This talk will describe our recent results utilizing energy filtered diffraction, 4D-STEM and in situ TEM nanomechanical testing that provide insight into multiscale deformation phenomena in α-titanium and the CrCoNi medium entropy alloy. Using energy-filtered TEM and HRSTEM techniques it is possible to directly image, and therefore quantitatively assess, SRO and its effect on mechanical properties. In order to understand the effect of SRO in terms of the evolution of plasticity at different stages, the technique of 4D-STEM was used during in situ deformation and fracture experiments. In addition to using these techniques to investigate deformation in medium entropy alloys, this talk will also describe effects related to SRO in pure Ti (a very low entropy alloy) and Ti-Al alloys. |
