Abstract
Pravilno in natančno izmerjene temperature so pomemben podatek za izvedbo in načrtovanje procesov na področju proizvodnih in metalurških tehnologij. V pilotnem laboratoriju smo pri procesih temperaturnega utrujanja jekel izvedli meritve temperatur na preizkušancih iz modificiranega jekla AISI H11. Izvedli smo simulacije temperaturnega utrujanja, izmerili temperature kritičnih točk testnega preizkušanca, analizirali rezultate izvedenih meritev ter predlagali ustrezne rešitve. Za testirano jeklo je process napredovanja razpok do 5000-ega cikla počasen, med 5000 in 10000 ciklom se pojavijo večje razpoke, po 10000 ciklu pa se širjenje oziroma napredovanje razpok ponovno upočasni.

Title:Temperature measurements at temperature fatigue of steel : diploma work
Abstract:
Correctly and precisely measured temperatures are important information for the implementation and planning of processes in the field of production and metallurgical technologies. In the pilot laboratory, during temperature fatigue processes of steels, we performed temperature measurements on test specimens made of modificated AISI H11 steel. We carried out simulations of temperature fatigue, measured the temperatures of the critical points of the test specimen, analyzed the results of the measurements and proposed appropriate solutions. For the tested steel, the crack propagation process is slow up to the 5000th cycle, between 5000 and 10000 cycles, larger cracks appear, and after 10000 cycle, the propagation or propagation of cracks slows down again.

Keywords:Temperature, measuring, steel, temperature fatigue.
