Stress corrosion cracking, hydrogen-induced cracking, hydrogen blistering, hydrogen embrittlement, hydrogen corrosion, corrosion fatigue, erosion corrosion, corrosion wear, etc. ================================ 【Mechanical Zone】Recruitment for moderators and technicians – applications and referrals are welcome.【Valid indefinitely】If you’re interested, come ahead! http://bbs.hcbbs.com/thread-1568748-1-1.html
Stress corrosion cracking, hydrogen-induced cracking, hydrogen blistering, hydrogen embrittlement, hydrogen corrosion, corrosion fatigue, erosion corrosion, corrosion wear, etc.
During use, the stresses acting on a material can arise from stretching, compression, bending, torsion, or from relative motion at the interface with the surrounding medium, as well as from the flow of high-speed fluids. Corrosion failure under the combined action of stress and corrosion includes: stress corrosion cracking, hydrogen-induced cracking, hydrogen blistering, hydrogen embrittlement, hydrogen corrosion, corrosion fatigue, erosion corrosion, corrosion wear, etc.
The failure phenomenon of materials, mechanical parts, or components resulting from the combined action of static stress (mainly tensile stress) and corrosion. It often occurs in boiler steel, brass, high-strength aluminum alloys, and stainless steel. Stress corrosion is also significant in components such as condenser tubes, steel cables used in mining, and the inner walls of high-pressure cylinders used for aircraft emergency braking. Chinese name: Stress Corrosion; English name: stress corrosion
