The microstructures and tensile properties of sintered Ti-4%Fe alloy compacts made by injection moldings were investigated. Specimens were made of Ti and carbonyl Fe powders with average diameters of 16 and 5 micrometer, respectively. Two kinds of binder systems containing 17.5% and 50% wax were used. The compacts were debound at 523K and 593K in air and then sintered at 1523K in vacua. The carbon content of sintered compacts decreased to 0.2% by using the binder system containing lower wax. Therefore, the microstructure of sintered compacts obtained by using the binder did not have TiC precipitates. The density of the sintered compacts increased by using finer Ti powder. The tensile strength of the sintered compacts was 230MPa.
