Abstract: A member produced by powder forging which retains machinability and improved fatigue strength without having an increased hardness and can retain self conformability after fracture splitting; a powder mixture for powder forging; a process for producing a member by powder forging; and a fracture splitting connecting rod obtained from the member produced by powder forging. The member produced by powder forging is one obtained by preforming a powder mixture, subsequently sintering the preform, and forging the resultant sintered preform at a high temperature. The free-copper proportion in the sintered preform at the time when the forging is started is 10% or lower, and the member obtained through the forging has a composition containing, in terms of mass %, 0.2-0.4% C, 3-5% Cu, and up to 0.4% Mn (excluding 0), the remainder being iron and incidental impurities, and has a ferrite content of 40-90%.
