DIFFERENTIAL HEAT SHAPING AND HARDENING USING INFRARED LIGHT

DIFFERENTIAL HEAT SHAPING AND HARDENING USING INFRARED LIGHT

A shaped part having at least two structural regions of different ductility is made from one unitary blank of a hardenable steel alloy by first heating the entire blank to an elevated temperature below an AC3 point of the alloy. Then only first regions of the blank are heated by a plurality of infra...

description A shaped part having at least two structural regions of different ductility is made from one unitary blank of a hardenable steel alloy by first heating the entire blank to an elevated temperature below an AC3 point of the alloy. Then only first regions of the blank are heated by a plurality of infrared lamps to above the AC3 point of the alloy while maintaining the rest of the blank below the AC3 point of the alloy. Finally the first regions are hardened in a thermoshaping and hardening tool.
