| Abstract Scope |
Steels possessing high yield strength and fracture toughness, like HY-80, are typically utilized in submarine applications. High impact toughness of submarine hulls is essential to prevent breaches caused by mild collisions at great depths. However, temper embrittlement is a phenomenon caused by the migration of impurity elements and carbides towards the grain boundaries during aging that can lead to decreased impact toughness and premature intergranular fracture posing a risk to the safety of the crew. Therefore, the purpose of the current study is to understand the microstructural evolution and the resulting impact on mechanical properties caused by temper embrittlement. In the current paper, five steel samples were heat treated at 525 °C for different holding times to induce varying degrees of temper embrittlement. These samples were then characterized by Scanning Electron Microscope (SEM), Electron Backscatter Diffraction (EBSD), Vickers Microhardness, and Charpy Impact tests. |
