High pressure deformation in two-phase aggregates
We investigate the rheological behavior of multi-phase aggregates at high pressure and high temperature. Using synchrotron X-ray radiation as the probing tool, we are able to quantify the stress state of individual phases within the aggregates. This method provides fundamental information in interpreting the behavior of two phase/multi-phase ...
Aggregation and deaggregation: The effect of high-pressure
Higher pressure (400–600 MPa) caused small particles to aggregate and form larger aggregates. Additionally, HPP treatment regulates aggregation behavior mainly by affecting the higher-order structure (tertiary and quaternary structures) of MRJPs, rather than by altering its secondary structure.
