Crack Growth Anomalies in Base Steel P91 and in HAZ

Authors: Jaroslav Balík, Miloš Janeček, Josef Pešička

Abstract: The growth of cracks in base steel P91 of 9Cr-1Mo class and in intercritical layer of HAZ is measured under creep coditions. For long term tests, a material degradation was detected consisting in an increase of crack growth rate and in a decrease of crack initiation time. An attempt is made to connect these effects with drop in ductility during thermomechanicalexposition.
