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 summed with applied stresses. Therefore, the development of a non-destructive testing (NDT) method that has the ability to rapidly monitor surface residual stresses has industrial importance when verifying the achievement of the design goals of shot peening. The utilisation potential of the magnetic Barkhausen noise (MBN) technique in shot peening of ferromagnetic steels includes automated sorting of the components and measurement of surface residual stress. This study aims to establish the correlation between MBN emission and the fatigue life of shot-peened AISI 4140 steel.

Determination of surface residual stresses in carburised AISI 8620 steel by the magnetic Barkhausen noise method Kaleli, T.; Gür, Cemil Hakan (British Institute of Non-Destructive Testing (BINDT), 2020-07-01) 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 carburise...
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, ...
Monitoring the microstructural changes during tempering of quenched SAE 5140 steel by magnetic barkhausen noise Davut, Kemal; Gür, Cemil Hakan (Springer Science and Business Media LLC, 2007-12-01) The aim of this work is to characterize the microstructures of quenched and tempered steels non-destructively by a diverse set of parameters of the Magnetic Barkhausen Noise method (MBN fingerprint, frequency spectra, pulse height distribution, root-mean-square, and total number of pulses). Identical specimens from a SAE 5140 steel bar were prepared. All specimens were austenitized at 860 degrees C for 30 minutes and water-quenched identically. The quenched specimens were then tempered at various temperatur...
Monitoring the Microstructural Evolution in Spheroidized Steels by Magnetic Barkhausen Noise Measurements DAVUT, Kemal; Gür, Cemil Hakan (Springer Science and Business Media LLC, 2010-12-01) The aim of this study is to monitor nondestructively the degree of spheroidization in steels by Magnetic Barkhausen Noise (MBN) method. Various series of specimens consisting of either lamellar pearlite or partially/completely spheroidized carbides were produced from AISI 1060 steel by appropriate heat treatments. All specimens were characterized by metallographic examinations, hardness and MBN measurements. The results show that MBN signals are very sensitive to the variations in the microstructure caused ...
The structural and electronic properties of BN and BP compounds and BNxP1-x alloys Mohammad, Rezek; Katırcıoğlu, Şenay (Elsevier BV, 2009-06-10) The structural and electronic properties of BN and BP compounds and BNxP1-x alloys have been investigated by full potential linearized augmented plane wave (FP-LAPW) method based on density functional theory (DFT). The total energies and electronic band structures of these compounds have been calculated for different approximations of exchange-correlation energy. The comparative study has showed that the Perdew-Wang-generalized gradient approximation (PW-GGA) is the best one to produce the measured structur...
