General Procedure of Failure Analysis: Macroscopy and Metallurgy

This course covers the comprehensive procedure of failure analysis and prevention, focusing on the macroscopic and microscopic examination of fracture surfaces. It delves into the importance of identifying the location and direction of failure, the type of loading conditions, and the stress state during failure. For instance, the presence of beach marks or changes in color could indicate exposure to corrosive environments or high temperatures. The course also discusses the significance of metallography in determining the class of the failed metal, its chemical composition, and the effect of service conditions. It further explains the different types of fractures such as fatigue fracture, tensile brittle fracture, and ductile fracture. The course uses examples such as the study of a failed steel component to illustrate these points.
