Sažetak
Dilatometry is a method of measuring changes in volume, length, width or thickness of the material sample during the time, caused by temperature changes. Through dilatometric testing of materials, it is possible to determine the dilatation behaviour of the material during heating and cooling. The device used to conduct dilatometric tests is called dilatometer. Through dilatometric testing of metals it is possible to determine the coefficient of thermal expansion (dilatation) and the characteristic temperature of microstructure transformation during heating and cooling. In the experimental part of the work, the dilatogram of diffusion annealing of maraging steel X2NiCoMo18-9-5 was recorded. Transformation temperature was read from the dilatogram and corresponding dilatations and the values of the coefficient of thermal dilatation during heating and cooling of maraging steel X2NiCoMo18-9-5 were calculated. Knowing transformation temperatures is necessary to determine parameters of the heat treatment. Using the coefficient of thermal dilatation it is possible, within certain temperature intervals, to predict dimensional changes of steel.
