the combined action of the tensile stress and specific ions in the corrosive media cause continual crack propagation with little evidence of local deformation. In austenitic stainless steel, for ...

Steel with a laminated nanosubstructure, like that seen in bones, is much more resistant to cracking that occurs from repeated stress, a new study reports. Development of steel and other alloys ...

Cracks can appear in stainless steel components when stress or strain is combined with a corrosive environment that attacks sensitive grain boundaries. These cracks represent a critical failure ...

Ethanol, however, is known for triggering stress corrosion cracking of steel. Researchers investigated the mechanism of how ethanol triggers stress corrosion cracking, along with ways to ...

According to conventional materials theory, applying stress to cracked metal should only expand those cracks. The new findings ... know whether alloys such as steel can perform this feat.

When hydrogen atoms enter the steel, they diffuse into its microstructure and can cause the metal to become brittle, making it more susceptible to cracking. Hydrogen can be introduced into the ...

While testing the creation of microscopic stress cracks in metals, the team observed something unexpected—one of the tiny cracks healed itself spontaneously without any human intervention.

(Bloomberg) — Electricite de France SA found indications that “stress corrosion” cracks may again affect pipes at a nuclear reactor that it fixed fewer than three years ago, risking a revival of ...
