Tensile strength and elongation of Fe-Sn system sintered compacts prepared by adding intermetallic compound Fe3Sn (2.7μ) into Fe powders were measured. The results obtained were as follows;<BR>1) Diffusion of Sn into Fe powders was extremely rapid. For example, by sintering at 890°C for 30 minutes Fe-2%Sn compacts pressed at 5t/cm<SUP>2</SUP>, completely alloyed structures were obtained.<BR>2) Mechanical properties of sintered compacts were distinctively affected by phase structure in the sintering and those which sintered in the field of γ-loop were excellent. Specimens sindered in the α-regions were extremely brittle.<BR>3) Tensile strengthes of compacts sintered in the field of γ-loop exhibited a linear relationship versus Sn-content at every temperature.
