Elementary Stereology for Quantitative Metallography

Indian Institute of Technology Kanpur and NPTEL via Swayam


Quantitative metallography or stereology is concerned with the measurement of microstructural features such as grain size, and the size and spatial distribution of second phase particles from the observations made on 2-D sections through optical, scanning and transmission electron microscopy. In all cases a small sample section or thin slice of material is observed in order to derive the microstructural characteristic of a bulk material. Stereology is therefore concerned with geometrical probability.INTENDED AUDIENCE:Anyone who is interested in the quantification of microstructuresPREREQUISITES: NilINDUSTRY SUPPORT:All materials related industries and Pathologists, Bio technologists
