| Abstract Scope |
The combination of nanomechanical testing and cryogenic temperature-capability enables the exploration of a rich variety of materials’ behaviors, from phase transitions in metals to glass transitions in polymers. Similar to the studies performed in the high temperature, high vacuum, regime, in situ cryo work requires that the tip and sample be and remain in equilibrium temperature for the test. Here, a study using two common alloys with applications for reliability in extreme cold/aerospace conditions, is presented. These materials show a range of nano/micromechanical behavior that varies as a function of the applied temperature, including a ductile to brittle transition that greatly affects structural reliability. |
