摘要： The object of the present invention is to provide a compact for producing a sintered alloy which allows a sintered alloy obtained by sintering the compact to have improved mechanical strength and wear resistance, a wear-resistant iron-based sintered alloy, and a method for producing the same. The wear-resistant iron-based sintered alloy is produced by: forming a compact for producing a sintered alloy from a powder mixture containing a hard powder, a graphite powder, and an iron-based powder by powder compacting; and sintering the compact for producing a sintered alloy while diffusing C in the graphite powder of the compact for producing a sintered alloy in hard particles that constitute the hard powder. The hard particles contain 10% to 50% by mass of Mo, 3% to 20% by mass of Cr, and 2% to 15% by mass of Mn, with the balance made up of incidental impurities and Fe, and the hard powder and the graphite powder contained in the powder mixture account for 5% to 60% by mass and 0.5% to 2.0% by mass of the total amount of the hard powder, the graphite powder, and the iron-based powder, respectively.

摘要： A thickened part is formed in the first member. The thickened part has a protruded part that is convex on one side in the thickness direction of the first member, so that the thick portion is set thicker than the general portion as the other portion. At least a part of the second member overlaps a part of the first member that includes the thickened part from another side of the first member in the plate thickness direction, and the self-piercing rivet is driven into a fastening overlapped part that is a part that the second member overlaps the thickened part from a second member side, so as to fasten the first member and the second member.
