Abstract Scope |
The combination of nanomechanical testing and cryogenic temperature-capability enables the exploration of a rich variety of materials’ behaviors, from ductile-to-brittle transitions in metals to glass transitions in polymers. Moreover, the highly localized measurements can target individual regions of the microstructure to evaluate their response and separate the response of thin films from their substrates. These capabilities can be used to study applied problems, like reliability of components for winter and aerospace applications, and theoretical ones by exploring deformation mechanisms across the time and temperature space. Two case studies will be presented, the determination of the glass transition temperature in polymer thin films utilizing dynamic indentation methods, and the phase-specific ductile-to-brittle transition characteristics of a plain steel. |
