タフトライド防止に及ぼす無機質コーティング剤の影響 : 第4報,切欠き半径による耐衝撃性の変化

抄録

In order to investigated the change of impact resistance by notch radius of steel protected from tufftriding by an inorganic coating, Charpy impact tests are carried out at various temperatures, using protectively coated specimens with notch radii of 1 R and 2 R for various treatment times. The impact transition curves, the transition temperatures and the fracture behavior are discussed by comparing them with both tufftrided and non-tufftrided steels.
