The paper describes an application of nondestructive volumetric magnetic and ultrasonic techniques for evaluation of the selected mechanical parameter variations of P91 steel having direct influence on its suitability for further use in critical components used in power plants. Two different types of deformation processes were carried out. First, a series of the P91 steel specimens was subjected to creep and second, one to plastic deformation in order to achieve the material with an increasing strain level up to 10%. Subsequently, non-destructive and destructive tests were performed. Magnetic methods based on measurements of magnetoacoustic emission and magnetic hysteresis loop changes as well as the ultrasonic method based on acoustic birefringence measurements, were applied. Finally, the static tensile tests were carried out in order to evaluate the mechanical parameters. It is shown that some relationships between the selected parameters coming from the non-destructive and destructive tests may be formulated.

“…Also complex approaches as e.g. [13,14] were described. The present paper intends to describe magnetic nondestructive measurement of three kinds of RPVS irradiated in the 10 MW Budapest Research Reactor at 290°C up to the fluence of 11.9 Â 10 19 n/cm 2 by highenergy neutrons (>1 MeV), which corresponds approximately to about 20 years of service of a pressure vessel in a WWER440 reactor.…”

“…In a variable magnetic field Hptq magnetic and electric material prop-erties are identified. The widest diagnostic possibilities of steel, cast iron and metal alloys have methods of magnetic Barkhausen noise (MBN), low-frequency spectroscopy of eddy currents (impedance) and 3MA (Micromagnetic Multiparameter Microstructure and Stress Analysis) [3,9,[16][17][18].…”

The paper has been intended to introduce a complex research problem, that is present in aviation, power engineering, mining and transport, with regard to assurance of operational safety for ageing technology, which is exposed to different form of material degradation. Theoretical reasons of non-destructive evaluation (NDE), structural health monitoring (SHM) and active control of material fatigue have been outlined. The magnetic and electromagnetic methods of NDE and SHM such as metal magnetic memory, low frequency eddy current spectroscopy, Barkhausen noise and 3MA have also been presented. The topic has been illustrated by means of practical examples.
