Abstract : TERIALS), (*ARMOR, CERAMIC MATERIALS), CERMETS, COMPOSITE MATERIALS, TITANIUM, TITANIUM COMPOUNDS, BORIDES, CARBIDES, BORON COMPOUNDSBORON CARBIDES, ARMOR, CERAMIC MATERIALS, TITANIUM BORIDEA study was made of the applicability of the impulse resistance sintering process to the production of ceramic armor material. An investigation of process variables demonstrated that resistive heating was enhanced by increased plunger length, a reduced plunger shank diameter, and a decreased die wall thickness. Conductive ceramics (TiB2), ceramic-metal mixtures (Ti plus TiB2), layered composites (Ti/TiB2), and metallized nonconducting ceramics (Ti on B4C powder) were resistance sintered. Densities approaching theoretical were achieved in times of the order of five minutes without the need for a protective atmosphere. (Author)
