Metallography is the field of scientific study devoted to the interrelationship between the structural characteristics and the physical and mechanical properties of metals and alloys as effected by composition, processing, and the service environment. Structural interpretation based on the visible characteristics of a fracture surface probably arose at the very dawn of metallurgy; this strategy was most likely used to control the composition of bronze for primitive axes. Modern metallography, mostly based on optical and electron microscopy, is important in maintaining close control over production processes for well-established materials, in basic materials research, in the development of new materials, and in failure analysis.
This course is intended to provide instruction in proper metallographic preparation techniques and the principles on which they are based. It describes methods of viewing structures and analyzing the constituents which are present.
This course has been enhanced with self-guided digital short courses added to related lessons. These additions feature enhanced visuals, narrated text and animations, and interactive quizzes to support learning.
