2903 温・熱間鍛造型の熱軟化及び塑性変形抵抗に及ぼす型の表面皮膜構造の影響(S31-1 新技術への取り組み,S31 塑性加工技術の動向とその展開)
詳細
The effect of thermal loads including frictional heat due to sliding velocity and the friction shear factor on the deformation resistance of forging tools with a hard coatling film was investigated using the finite element method. Temperature distribution in the tool was calculated by thermal analyses, taking into consideration frictional heat generated by frictional sliding. Plastic deformation of the tool was evaluated according to the distribution of flow stresses obtained from the temperature distribution.
