Advanced experimental measurements of heterogeneous strain and temperature change in metals
This work investigates elevated temperature deformation in the nickel-based superalloy Haynes 230 and elastocaloric cooling in shape memory alloys. Three loading conditions were examined in the elevated temperature portion: fatigue crack growth, creep, and tension. Measurements were made on varying …

Elevated temperature mechanical properties of line pipe steels
The effects of deformation temperature near the dynamic strain aging (DSA) regime on the tensile properties of X70 and X52 line pipe steels were evaluated. Testing temperatures of interest were in the range of 25 to 350 °C, at engineering strain rates in the range of approximately 10 4 to 10 3 s 1. …

Multiscale In-Situ Characterization of Crystal Orientation, Temperature, and Microstructure Effects on Creep Defromation of Pure Magnesium and Mg-Al-RE Alloys
… resistance and pronounced anisotropy of plastic deformation, especially at elevated temperatures. This thesis examines how crystal orientation, temperature, and β-phase morphology govern creep behavior in pure Mg and AE44 alloys. Novel in-situ nanoindentation creep methods were developed using an …
