Management of the residual stress state is vital for the design and production stages of carburised components in order to satisfy the technical requirements related to performance, fatigue behaviour and useful lifetime. This enforces the use of practical, reliable and time- and cost-effective stress measurement methods by manufacturers. This study aims to investigate the efficiency of the magnetic Barkhausen noise (MBN) method in rapid non-destructive determination of surface residual stresses in carburised steels. A series of AISI 8620 steel specimens with different residual stress states was prepared by altering the carburising and subsequent tempering parameters. The specimens were characterised through scanning electron microscopy (SEM) investigations and hardness measurements, and the surface residual stresses were determined using both the MBN and X-ray diffraction (XRD) methods. The results show that a good correlation exists between surface residual stress and the parameters derived from the MBN signals.

Investigating the correlation between magnetic Barkhausen noise emission and the fatigue life of shot-peened AISI 4140 steel Çalışkan, S.; Gür, Cemil Hakan (British Institute of Non-Destructive Testing (BINDT), 2019-01-01) The performance of engineering components under conditions of fatigue can be improved by shot peening. The location and magnitude of the highest residual compressive stress, the depth of the compression zone and the stability of the residual stress state during cyclic loading are critical parameters for maximum utilisation of the advantageous influence of shot peening on fatigue performance. For accurate assessment of fatigue lifetime, residual stresses should be considered because they are algebraically su...
A STUDY OF IMPURITY EFFECT ON ORDERING CHARACTERISTICS OF FE3AL INTERMETALLICS Mehrabov, Amdulla; Ozturk, T (Elsevier BV, 1994-03-01) A study is carried out into energetical and structural characteristics of atomic ordering processes in Fe3Al. The statistico-thermodynamical theory of ordering by a quasichemical method is combined with the electronic theory of alloys in pseudopotential approximation in order to predict impurity effects on DO3 double-line arrow pointing left and right B2 phase transition temperature and the characteristics of atomic short-range order in Fe3Al-type intermetallics. Impurity elements in Fe3(Al, Me) Me-Cr, Si, ...
Determination of trapping center parameters of Tl2InGaS4-layered crystals by thermally stimulated current measurements Mogaddam, Nader A. P.; Yuksek, N. S.; Hasanlı, Nızamı; Ozkan, H. (Elsevier BV, 2006-06-29) We have carried out thermally stimulated current measurements on as-grown Tl2InGaS4-layered single crystals in the low temperature range 10-60 K with different heating rates. We found experimental evidence for the presence of two shallow hole trapping centers with activation energies of 4 and 10 meV. We have determined the trap parameters using various methods of analysis, and these agree with each other. Their capture cross-sections have been found to be 6.5 x 10(-26) and 4.0 x 10(-25) cm(2), respectively,...
Effect of vanadium on atomic ordering characteristics and anti-phase boundary energies of B2-FeCo alloys AYKOL, Muratahan; Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (Elsevier BV, 2010-05-01) Effect of V on the energetical and structural characteristics of atomic ordering processes of B2-FeCo intermetallics have been investigated via electronic theory of multi-component alloys combined with Monte Carlo (MC) simulations. Emphasis has been placed on the variation of anti-phase boundary (APB) energies with V content and temperature to establish a relationship between ductility and atomic ordering characteristics of (FeCo)(100-x)V(x) (x = 0-5 at%) alloys. It was shown that APB energies are highly af...
Microstructural investigation of SAE 1040 steel specimens by ultrasonic measurements Gür, Cemil Hakan (British Institute of Non-Destructive Testing (BINDT), 2005-07-01) The aim of this study is to characterise the microstructures of the as-quenched and tempered SAE 1040 steel specimens by sound velocity and attenuation measurements. An initial heat treatment was applied to the specimens to obtain a uniform starting microstructure. Following 850 degrees C/0.5 h austenitisation and water-quenching of all specimens, a tempering process was applied at 200 degrees C and 600 degrees C for 2 h. Microstructures of the specimens were characterised first by metallography and hardnes...
