| Abstract Scope |
The need to observe events happening in the TEM, rather than just characterize the defects involved, has a long history going back to the first TEM observation of dislocations moving by Mike Whelan. Our collaboration with Bill Gerberich began with a study of small particles and subsequently led to the first observation of individual nanoparticles being elastically deformed and fractured in the TEM. Bill’s extensive understanding of fracture mechanics and deformation was key to understanding these processes; this study was then extended to interfaces. Prof. Gerberich had secured funds that led to the construction of the original Hysitron (now Brucker) TEM deformation holder. This talk will consider the current state of in-situ TEM experiments, including fracture and deformation at the highest resolution, and some possible future developments. Bill Gerberich applied his deep understanding of plasticity theory to extract the most from experimental studies of deformation and thereby inspired us all. |
