| Abstract: | The macrotexture and mechanical properties of porous Al2O3/Al metal ceramics prepared by the hydrothermal treatment of aluminum powder in a closed space are studied using gravimetry, pycnometry, mercury porosimetry, and scanning electron microscopy. Analytical expressions that relate the porosity, density, and mechanical strength of parent materials and final products to the composite synthesis conditions are derived. |
