Effect of Surface Treatment on Warm Forging Die
Synopsis Recently, a warm forging process is remarkable from the points of view in near net shaping and abolishment of additional heat treatment by micro-structural controlling. In generally, a die life in forging decreases accompany with the increase of forging temperature. The die life in hot forging is only about 1/10 1/100 compared with that in cold forging, because of the serious heat damage. The die life in warm forging is normally about same level of that of hot forging in spite that itdoi:10.4262/denkiseiko.78.207 fatcat:2ps2fgbfrjbh7hwrnvcosi33ae
