Abstract

PURPOSE: To enable mechanical parts of superior dimensional accuracy, weight accuracy and mechanical properties to be produced inexpensively and highly efficiently by heating the green compact which is formed of cast iron powder as its main material and forging the same to the specified shape, then sintering the same.
CONSTITUTION: Metal powder such as of Cu, Al, Ti, Ni, Cr, Mn, etc., if necessary, and lubricant such as metal soap, etc. are added and mixed to cast iron powder. This raw material powder is put in dies and is pressure-molded with a press machine. This green compact is heated through high frequency induction heating, etc. in a nitrogen gas atmosphere, to let the lubricant, etc. evaporate. Next, the heated green compact is put in dies and is hot-forged to be formed to the final shape, after which it is sintered in an atmosphere such as of propane gas, etc. The sintering temperature and time are generally 1000 to 1500°C, 10 to 45 minutes. Thereafter, the molding is subjected to machining, if necessary and post treatment such as hardening and tempering.
