QUENCHING DILATOMETER RITA L78

This practice is based upon the principle that, during heating and cooling of steels, dimensional changes occur as a result of both thermal expansions associated with temperature change and phase transformation. In this practice, sensitive high-speed quenching dilatometer equipment is used to detect and measure the changes in dimension that occur as functions of both time and temperature during defined thermal cycles. The resulting data are converted to discrete values of strain for specific values of time and temperature during the thermal cycle. Strain as a function of time or temperature, or...

Operation Method Operation Method of Quenching Dilatometer A solid or hollow sample is continuously heated to a certain temperature plateau. At this plateau a continuous cooling is started. The cooling is repeated at different (linear or exponential) cooling rates. The phase transformations occurring in the different cooling cycles are indicated by the measured change of length. An array of cooling curves with different cool down cycles represents a continuous or isothermal TTT diagram (Time Temperature Transformation diagram). Start and stop of the transformation define the fields of e.g. ferrite,...
