Corrosion Fatigue Cracking and Metallurgical Embrittlement of Metals

Corrosion is the primary and major cause of metal and structural failure worldwide. Trillions of dollars are spent every year to replace structures attacked when not completely demolished by corrosion and by related mechanisms like corrosion fatigue and hydrogen embrittlement. Metals, like high strength steels, stainless steel, nickel alloys or aluminum alloys, developed to resist general corrosion reveled to be very sensitive to localized corrosion and to fail in matter of months or even days.

Course Description

This course explores the fundamentals of localized corrosion and related mechanisms like corrosion assisted fatigue, environmental embrittlement of metals, such as stress corrosion cracking, metal sensitization and hydrogen embrittlement. Though electrochemical phenomenon, corrosion is treated with the aids of mechanical tools provided by fracture mechanics. Participants will have the opportunity to learn from over 40 years of experience of the instructor.

Objectives

 At the end of this workshop the participants should be able to:

• Demonstrate a comprehensive understanding of corrosion fundamentals and related mechanisms such as stress corrosion cracking, metal sensitization and hydrogen embrittlement

• Gain confidence in preventing corrosion by using adequate and advanced corrosion control and prevention tools.

Topics Covered

• Elements of electrochemistry
• Temperature and cold work sensitization of austenitic SS, nickel and aluminum alloys
• Hydrogen embrittlement
• Fracture mechanics approach to corrosion
• Stress corrosion threshold
• Constant extension rate test
• Corrosion in welds and be-metallic coupling
• Environmental fatigue
• Fatigue assisted corrosion and crack growth rate
• True corrosion fatigue

Who Should Attend

Engineers and other professionals interested in corrosion, environmental fatigue and hydrogen embrittlement and sensitization to corrosion.
