Z PHASE STABILITY IN AISI 316LN + Nb AUSTENITIC STEELS DURING CREEP AT 650°C

Popis výsledku v původním jazyce

The creep resistance of austenitic CrNi(Mo) steels strongly depends on microstructural stability during creep exposure. One of the most successful methods of improving the long-term creep resistance of austenitic steels is based on increasing the extentof precipitation strengthening during creep exposure. The role of precipitates in the achievements of good creep properties has been extensively studied for a long time. Although many minor phases are now well documented there are still contradictions and missing thermodynamic data about some minor phases. This contribution deals with results of microstructural studies on the minor phase evolution in wrought AISI 316LN + Nb steels during creep exposure at 650°C. The attention has been paid to evaluationof thermodynamic and dimensional stability of Z phase and other nitrogen bearing minor phases. Only two nitrogen-bearing minor phases formed in the casts investigated: Z phase and M6X. The dimensional stability of Z phase particles was v
