## Description

- description: 沸騰水型原子炉を模擬した高温高圧水中環境下では、溶存酸素量(DO)の変化により動的ひずみ時効(DSA)と粒界型応力腐食割れ(粒界SCC)がそれぞれ発生する。これらの現象の違いを明確に理解するために、その発生メカニズムを整理した。その結果、SUS304ステンレス鋼では、DOが1ppb未満の低濃度では粒内割れによるDSAが発生し、DOが100～8500ppbでは表面の酸化膜形成によりDSAは抑制されることがわかった。一方、DOが20000ppbまで上昇すると、皮膜が母材から剥離し、母材の結晶粒界に酸素元素が拡散し、粒界SCCが発生した。これらの結果から、DSAや粒界SCCによるクラック発生を抑制するためには、最適なDO濃度を調整する必要があることがわかった。
