DBTT measurement by use of small punch(SP) test
DBTT measurement by use of small punch(SP) test微小試験片による延性脆性遷移温度(DBTT)の評価法について、スモールパンチ(SP)試験を中心に検討を行った。熱時効、冷間加工、中性子照射を行った21/4Cr-1Mo鋼及び鉄基モデル合金を用い、SP試験によるDBTT評価の課題を検討した結果、SPによるDBTTとシャルピー試験によるDBTTは全般的には良い相関が得られた。しかしながら、粒界脆化型のDBTTの上昇に関しては、SP試験片の破壊破面観察等を組み合わせることにより、脆化のより的確な判断を行っていく必要があることが判った。
