Properties and microstructure of modeled heat-affected zone of P92 steel
Original language description
This paper is focused on the modelling of the heat-affected zone of steel P92 during one layer TIG (141) welding. Simulation of the heat-affected zone (HAZ) was performed on the thermal cycle simulator of its own design. The test results of mechanical properties of the modelled HAZ are compared with the results obtained on real welded joints. Critical parts of ultra-supercritical (USC) boilers are welded joints. This significantly affects the operational reliability and service life of components in USC blocks. Therefore, this work is focused just on the research of the properties of HAZ of P92 steel. The thermal cycle simulator allows transferring the properties of very small HAZ to the sufficiently large sample where the tests of the mechanical properties can be performed. Satisfactory accordance was found when comparing the microstructure and mechanical properties of real welds and simulated samples.
