Abstract
The macrotexture and mechanical properties of porous Al2O3/Al metal ceramic s prepared by the hydrothermal treatment of aluminum powder in a closed spa ce are studied using gravimetry, pycnometry, mercury porosimetry, and scann ing electron microscopy. Analytical expressions that relate the porosity, d ensity, and mechanical strength of parent materials and final products to t he composite synthesis conditions are derived.
