Suppression of fatigue crack propagation with hydrogen embrittlement in stainless steel by cavitation peening

Investigation of Hydrogen Diffusion Profile of Different Metallic Materials for a Better Understanding of Hydrogen Embrittlement

“…By introducing hydrogen into the material microstructure through cathodic charging, researchers can study the effect of hydrogen on properties such as tensile strength, ductility, fracture toughness, and impact properties. [18][19][20][21]. However, it is important to understand how the hydrogen content and distribution in the specimens changes with charging time, temperature, and hydrogen diffusivity of the materials.…”

Preventing hydrogen embrittlement in stainless steel by means of compressive stress induced by cavitation peening

“…So, there is a possibility that hydrogen invasion and diffusion can be controlled. Recently, it was reported that introduction of compressive residual stress may be an effective way to prevent hydrogen embrittlement cracking [4, 5]. In this report, cavitation peening was performed to introduce compressive residual stress.…”

Suppression of Fatigue Crack Propagation of Duralumin by Cavitation Peening

“…Soyama has succeeded in controlling cavitation bubbles collapsing in jet, i.e., cavitating jet, in order to modify the surface of metallic materials for improving the fatigue strength. The peening technique utilising the impact produced by cavitation bubble collapsing is called “cavitation shotless peening [2–5]” as shots are not required or simply “cavitation peening [6, 7]”.…”
