This training course is designed to give a semi-detailed discussion of Metallurgical failure analysis in order for the course material to suit participants with or without a metallurgical background. The course is divided into three main areas: Analysis methodologies and investigation techniques, Failure modes and mechanisms and Failures involved in different engineering parts. In addition several case studies are explained to the audience and discussion of case studies which might have been encountered by some of the participants.
By the end of this course delegates will be able to:
- To familiarize participants with the main tools and equipment used for metallurgical failure analysis.
- To introduce participants to different types of failures.
- To explain to participants the relationship(s) between design aspects, loading and/or manufacturing techniques and the different types of failures.
- To train participants to carry out a systematic failure analysis of filed parts.
- To describe and enhance necessary skills needed for successful failure analysis.
- To help the participants prevent future failures by proper inspection and or operation practice
- To train participants how to prepare a failure analysis report
