Tartalmi leírás:
In the present paper we summarize some of our results obtained in the field of magnetic
testing of thermal shock fatigue testing of power plant steels. In this work 15Mo3 type ferritic heat
resistant steel was investigated. This steel and several similar grades are commonly used in power
plants boilers as the material of reheating steam pipelines and pressure vessels. Their typical
application temperature is about 500-550 °C. It is commonly accepted that a combined form of
mechanical, thermal fatigue and the creep processes causes the long term deterioration of this
structural steels. The applied thermal shock fatigue test can model the material degradation due to
long term service in high temperature environment. A parallel motion vibrating sample
magnetometer, an AC permeameter and a magnetic Barkhausen noise measuring device was used
for testing the magnetic properties of the samples and several different magnetic properties were
measured to characterize the microstructural processes of the deterioration.
