Vliv deformace na rozpadový diagram eutektoidní oceli legované chrómem

Abstract

The submitted thesis deals with the effect of deformation on CCT diagrams of chromium-alloyed eutectoid rail steel application. The CCT diagrams with and without previous deformation were constructed on the basis of dilatometric tests with the application of universal plastometer Gleeble 3800 and in combination with a series of metallographic analyses and hardness measurements. The effect of previous deformation on each type of phase transformation from austenite during different cooling cycles could have been assessed.
