Mechanical damage evolution mechanism of coal injected with supercritical CO2 using Nanoindentation and XRD-EPMA technology
Published 2025-07-01“…In the process of ScCO2 solution leaching, the coal gradually changes from elastic deformation to plastic deformation, the nano indentation crack expands rapidly, the micro morphology of the coal surface is seriously damaged, and the creep deformation increases linearly. The dissolution reaction changes the pore structure and elastic-plastic transformation of coal, enhancing the discreteness of the nanoindentation load curve and causing an increase in the frequency of popping events. …”
