Structure examination : lecture notes

Abstract

The lecture notes Structure Examination provide a systematic overview of the methods and principles used to investigate the structure, properties, defects and failure mechanisms of metallic materials and machine components. The course covers the fundamentals of materials science and metallurgical examination, destructive and non-destructive testing methods, fractography, and the principles of metallographic analysis. Particular attention is paid to the examination of welded joints, the formation of weld microstructures, the identification of defects, and the determination of the causes of cracking and fracture in metal components. The course also addresses the methodology for investigating the causes of machine-part failure, including the assessment of material quality, manufacturing technology, operating conditions and loading factors. The acquired knowledge provides a basis for interpreting investigation results, establishing the causes of material and component failure, evaluating their service suitability, and developing recommendations to improve the reliability and durability of engineering structures and machine parts.
