Abstract

V magistrski nalogi smo analizirali vpliv toplotne obdelave TVP na udarno žilavost. Obravnavali smo temperaturi 760°C in 780°C, ter različne čase toplotne obdelave. Simulirali smo različna področja TVP, ki se pojavijo pri varjenju. Preizkušance smo ustrezno toplotno obdelali ter jih nato preizkusili z instrumentiranim Charpy preizkusom. Pri tem smo dobili podatke o udarni žilavosti materiala. Podatke smo med sabo primerjali in ugotavljali najbolj primerno temperaturo in čas toplotne obdelave, pri kateri dosežemo ustrezno udarno žilavost materiala. Pokazalo se je, da že majhna sprememba temperature pomembno vpliva na čas toplotne obdelave.

Secondary title: Influence of HAZ heat treatment on impact toughness on steel P91
Secondary abstract: In the thesis, we analyze the influence of heat treatment TVP on the impact toughness. We have considered the temperature of 760°C and 780°C, as well as various times of heat treatment. We simulated the different areas of TVP that occur during welding. The samples were properly heat treated and then tested with an instrumented Charpy test. We get information of the impact toughness of the material. Data were compared and identify the most suitable temperature and time for heat treatment in which to achieve adequate impact toughness of the material. It has been shown that even a small change of temperature has a significant influence on the time of heat treatment.
