Correlative In-situ/Ex-situ Approaches to Reveal the Mass Transport Mechanisms During Shear Deformation
EMSL Project ID
60229
Abstract
Solid phase processing (SPP) of alloys using multi-scale shear-deformation produces not only enhanced mechanical properties, but also results in nanoscale metastable phases. Revealing mass transport at very high strain during such process makes the atomic-scale mechanisms in SPP quite complex to understand in real time. Hence, as a part of SPP drive in PNNL, we use cluster of shear deformation capabilities ranging from a tribometer (macroscale), in situ rotational diamond anvil cell (RDAC), atomic force microscopy (AFM) and in situ shear deformation (nanoscale) in focused ion beam/transmission electron microscope to emulate localized shear deformation conditions and characterize microstructures before-after processing using advanced multimodal microstructural characterization.
