| Abstract: | The effect of uniform pressure and temperature on voids and cracks located at grain boundaries in polycrystalline metals is studied. A high-sensitivity method for measuring density, scanning electron microscopy, and optical microscopy were used to analyze the healing of cavities. The results obtained are discussed on the basis of the existing notion of the kinetics of healing under pressure at various temperatures. |
