CREEP CAVITATION BEHAVIOUR OF P91/P92 STEELS DURING LONG-TERM CREEP TESTS

Popis výsledku v původním jazyce

The presence and importance of cavitation damage and fracture during creep of Cr-Mo-V creep resistant steels (including martensitic grades) increases with increasing temperature and time to fracture, and at the same time, a decrease in fracture elongation can also be observed. In the case of uniaxial creep tests, the area and distance from the fracture line where the cavitation can be detected while its intensity gradually decreases also increases.The creep cavitation behaviour of P91 and P92 steels was monitored in a series of creep tests performed in the temperature range of 575 to 625 °C and with a time to fracture of up to 35,000 hours. The extent of cavitation damage was assessed, depending on the distance from the fracture line, according to the procedure according to NORDTEST TR 302, in which classification into individual damage classes is based on a quantitative assessment of the number of cavities, or length of chains of cavities and/or microcracks.
