abstract = "Broken test tubes for low-cycle fatigue testing of Nionicral 70 (NN-70) parent material (PM) steel
and simulated heat-affected zones (SHAZ) were used to produce samples for cavitation resistance
testing. Ultrasonic vibrational cavitation method (stationary sample method) was applied for
testing in laboratory conditions. The test conditions and procedure, sample preparation and
interpretation of results are defined by ASTM G32. The surfaces of the NN-70 PM and SHAZ steel
samples were exposed to cavitation and damage monitoring over time. Measuring the weight loss of
samples on the analytical balance after a certain time allowed us to determine the cavitation
velocity as a measure of the material's resistance to the effect of cavitation. Scanning electron
microscopy (SEM) was applied to monitor variations in surface morphology with changing test
time. On the basis of the results of the cavitation resistance test, the morphologies of the surface
damage for different exposure times of the cavitation of PM and SHAZ steel NN-70 samples were
analyzed, as well as the mechanisms that led to the damage of the sample surfaces.",
