In Situ Transmission Electron Microscopy for Ultrahigh Temperature Mechanical Testing of ZrO.

This work demonstrates a novel approach to ultrahigh-temperature mechanical testing using a combination of in situ nanomechanical testing and localized laser heating. The methodology is applied to characterizing and testing initially nanograined 10 mol % ScO-stabilized ZrO up to its melting temperature. The results suggest that the low-temperature strength of nanograined, < 50 nm, oxides is not influenced by creep.
