Monitoring variation of surface residual stresses in shot peened steel components by the magnetic Barkhausen noise method SAVAŞ, SERDAR; Gür, Cemil Hakan (2010-12-01) Shot peening is a cold working process by which residual compressive stresses are induced in the surface and near-surface region to increase the fatigue strength and the resistance to stress corrosion cracking This study covers non-destructive evaluation of surface residual stresses in the shot peened steel components by the magnetic Barkhausen noise method For this purpose various sets of steel specimens were prepared by a controlled shot peening process with different intensities impact angles and coverag...
Monitoring variation of surface residual stresses in the shot peened steel components by magnetic barkhausen noise method Savaş, Serdar; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2010) Shot peening is a cold-working process by which residual compressive stresses are being induced in the surface region to increase the fatigue strength and the resistance to stress-corrosion cracking. This study covers non-destructive measurement of surface residual stresses in the shot-peened steel components by a micro-magnetic technique, named as Magnetic Barkhausen Noise (MBN) method. For this purpose, various low alloy steel specimens were prepared by a controlled shot peening process with different int...
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 ...
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 rheological properties and solid content of selected food materials contained in cylindrical cans using audio frequency sound waves Mert, Behiç (Elsevier BV, 2007-03-01) The attenuation of the sound energy produced by a liquid contained in a cylindrical shaped container depends on the liquid's viscosity, the sound frequency, and the tube wall thickness. By measuring the acoustic impedance caused by the interaction of sound waves moving in a system composed of a liquid material in a cylindrical shaped container information about the viscosity of the liquid material was obtained. Impedance measurements can also provide sound velocity in the liquid medium as another important ...
