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 ...

Mimicking the crack-resistant properties ... the nanostructure of two types of steel to mimic the multilayered structure of bone. When subjected to standard stress patterns, the new materials ...

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 ...

They just had a ‘feel’ for avoiding undue stress. But probably they were ... What the crash did was to cause the already stressed steel to crack. “We believe the damage to the ship consisted ...
