Experiment: Metallography Specimen Preparation and ...
imechanica.orgMetallography consists of the study of the constitution and structure of metals and alloys. Much can be learned through specimen examination with the naked eye, but more refined techniques require magnification and preparation of the material's surface. Optical microscopy is sufficient for general purpose examination;

Continuous Cooling Transformation (CCT) Diagrams
www.phase-trans.msm.cam.ac.ukby metallography and hardness measurement. In dilatometry the test sample (Fig. 1) is austenitised in a specially designed furnace (Fig. 2) and then controlled cooled. Sample dilation is measured by dial gauge/sensor. Slowest cooling is controlled by furnace cooling but higher cooling rate can be controlled by gas quenching. 3
