シャルピー衝撃試験によるボロン添加ステンレス鋼の破壊じん性評価

抄録

Charpy impact tests were performed for borated stainless steel in the present study. In order to investigate the effect of strain rate on the fracture toughness, starting position of a hammer was reduced until complete fracture did not occur. Impact strains were measured on the specimen and the fracture mechanisms were studied.
