Název v původním jazyce

Creep properties of heat affected zone in heterogenous welded rotor

Popis výsledku v původním jazyce

Increasing demand on efficiency and power output of steam generators leads to new designs of welded rotors. The reason for rotor welding is the large size of rotors, which are difficult to produce in a single piece. Secondly, as there are varying operation conditions along the rotor length. In a heterogeneous rotor, several materials appropriate for local service conditions can be used. At the rotor service temperatures, creep properties are crucial for successful design. The weakest point of every welded component is the heat affected zone. Therefore, the creep properties of a heterogeneous weld are subject of the investigation here. In the current study, a heterogeneous weld of COST F and COST FB2 materials is investigated. The welding was performedby multi pass technique with overlaying welding beads that applied several heating cycles to heat affected zone. Metallographic investigation of the weld was performed and the weakest microstructure spots were detected. With the use of FE
