Description

A ceramic with a high fracture toughness KIC that is close to the respective values of cast iron and Mg alloys has been fabricated by microwave sintering of GdAlO3 and ZrO2 into composite materials of different molar fractions; for the 80/20 composite KIC reaches the remarkable value of 17.5 Mpa m1/2. Such composites may become extremely valuable for structural applications in advanced technologies. (Abstract Copyright [2003], Wiley Periodicals, Inc.)
