In this paper the author describes some of the effects of the operation for rivet-making and riveting on the mechanical properties and microstructures of high tensile steel rivets. The effects on mechanical properties was studied by means of tensile, hardness, and impact tests. The resuets of the investigation indicate that (1) the overheating accentuates the blue-brittleness, secondary-brittleness and transformation-brittleness of high tensile steel rivet bar, (2) the high tensile rivets always decrease in tensile strength and elongation with the clenching operation within the blue-brittleness and secondary-brittleness range, and (3) the best temperatures of heating will be as follows : - For rivet-making, 900℃ For pneumatic riveting, {1, 050℃-(10∿30 sec) when heated by an electric furnace, 1, 100℃-(1∿3 sec) when heated by a coke firing furnace.
