by 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

Time Temperature Transformation (TTT) Diagrams

The time taken to 1% transformation to, say pearlite or bainite is considered as transformation start time and for 99% transformation represents transformation finish. On quenching in water austenite transforms to martensite. But below 230 C it appears that transformation is time independent, only function of temperature. Therefore after

Metallography 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;
