High pressure phase transformation evolutions are able to be tracked using diamond anvil cell testing during in situ synchrotron X-ray diffraction. This method of identifying deformation mechanisms can be applied to metastable complex concentrated alloys (CCAs), specifically transformation-induced plasticity (TRIP) CCAs, which absorb high strain rate loads due to TRIP activation during loading. Two systems will be explored in this presentation, including FeMnCrCoSiCuV and FeMnCrCoSiCu. The results of the phase evolution as high pressures are induced will be discussed, as well as the effects of using powder samples rather than bulk. The sample preparation and experimental setup for this technique will also be presented.
