The residual stress state has a vital effect on the performance and service life of the welded structures. Thus, development of rapid and reliable nondestructive techniques to measure residual stresses is a critical task. Various destructive or nondestructive methods exist with their advantages and limitations. This study aims to investigate the applicability of Magnetic Barkhausen Noise (MBN) method to monitor the residual stress variations in the spiral welded steel pipes. In the experimental part, API 5L X70M steel was welded by submerged arc welding technique. Variation of the surface residual stresses was detected by MBN measurements. Microstructure investigations, hardness measurements, and residual stress measurements by the X-ray diffraction method were performed.

Non-Destructive Determination of Surface Residual Stresses in the Carburized SAE 8620 Steel Components
Kaleli, Tuğçe; Gür, Cemil Hakan (2018-12-26)
Management of the residual stress state has critical importance for fatigue life of the carburized steel components. The conventional methods of residual stress measurement are either destructive or have limited ability for in-situ measurement or take considerable time. Hence, there is a need for rapid, practical and reliable non-destructive method for measurement of residual stress. The aim of this study is to investigate the efficiency of the magnetic Barkhausen noise (MBN) method for evaluation of the su...
Nondestructive monitoring of the variations in microstructure and residual stress in carburized steels
Hızlı, Hüseyin; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2016)
Service life and performance of the case-hardened machine parts are greatly dependent on the residual stress state in the surface layers which directly affects the fatigue behavior. Recently, all industrial sectors have been requested for a fast and non-destructive determination of residual stress. This study aims to monitor the variations in surface residual stress distributions in the carburized 19CrNi5H steels by means of non-destructive and semi-destructive measurement techniques, Magnetic Barkhausen No...

PREDICTION OF SURFACE RESIDUAL STRESSES IN BUTT-WELDED STEEL PLATES BY MAGNETIC BARKHAUSEN NOISE ANALYSIS
Gür, Cemil Hakan; Yelbay, Hasan İlker; Çam, İbrahim (2010-06-11)
Residual stresses have significant inflences on the service performance of the welded components. Various studies have been continuing to develop nondestructive methods for determination of residual stresses with portable equipment and short measurement time, as an alternative to the existing techniques such as X-ray diffraction. This study aims to investigate the applicability of Magnetic Barkhausen Noise method on predicting surface residual stresses in the welded steel plates.
Sensitivity Analysis of Distortion of Carburized Steel Shafts Using Computer Simulations
Yazır, Büşra; Evcil, Elif; Yıldız, Seçil; Davut, Kemal; Şimşir, Caner (null; 2016-12-01)
Carburizing and subsequent quenching heat treatments are commonly used industrial processes to improve the properties and performance of steel shafts. Undesired dimensional and shape changes (distortion) related to these treatments are still the most frequent reason for expensive and time consuming corrective operations, low performance during service and even product rejection. The major aim of this study is to identify the suitable control parameters for subsequent optimization of the carburized quenching...
