Abstract

VOROBEL, Determination of thermal cycles. Master thesis. Ostrava: VŠB – Technical University of Ostrava, Faculty of Mechanical Engineering, Department of Mechanical Technology, 2010, 54 p. Thesis Supervisor: Schwarz, D. This master thesis focuses on analyzing welding temperature cycles of creep-resisting martensitic 9% chromium steel P92. The objective of the thesis lies in setting up the appropriate temperature cycles for welding of P92 steel and their simulation on P92 steel samples. Simulation was performed for thermally affected area, specifically for the overheating zone, the normalization zone, and the zone of partial-recrystalization. In the experimental part of this master thesis, mechanical characteristics and structural changes of P92 steel were studied through TOO zones mentioned.
