Microstrain and grain-size analysis from diffraction peak width and graphical derivation of high-pressure thermomechanics

By analyzing diffraction peak profiles at different P–T loading stages, the thermomechanical properties of materials can be derived, with graphical delineations of micro/macro yields, plastic flow, energy dissipation, work hardening/softening, grain crushing/growth, stress relaxation and residual strain, as well as instrument baselines for all diffraction modes.
