ボロン添加ステンレス鋼の破壊じん性に及ぼすひずみ速度の影響

抄録

Fracture toughness tests were performed for borated stainless steel in the present study. Fracture resistance curves were determined by the unloading elastic compliance method based on the ASTME1820 as well as an image processing technique. The latter was applied to investigate the effect of strain rate on the fracture toughness using split Hopkinson bar method.
