Abstract
Fe-Al intermetallic compounds were manufactured by using the field-activated combustion synthesis process. Effects of chemical composition(Fe:Al=1:2, 1:1, 21), compaction pressure(150. 250, 350㎫) and electrical resistance on the reaction were investigated. As the molar ratio of Al, compaction pressure and electric field increased, the combustion temperature and velocity increased. The structure and composition of reaction products were characterized with X-ray, SEM and EDXS to determinethe. As a results, final product was influenced with the composition of reactants, but was not influenced with compression presure.
