Abstract
An application of failure analysis procedure was performed on two case studies. The
first case is a chain conveyor link which broken in a brittle manner due to its brittle
phase and presence of large portion of nonmetallic inclusions and linear defects which
were a preferred site for fatigue crack initiation.
The second case is a fire water pipe which experienced a leakage. Analyzing the
obtained data and results of performed examinations demonstrated that the cause of
failure is a damage happened to the pipe lining which led to initiation of a corrosion pit
and this localized corrosion was aggravated by microbiologically influenced corrosion,
chloride ions and oxygen cell.
