Carburizing is widely used to improve wear resistance and fatigue life of high duty machine parts. Fatigue performance of the carburized components is greatly dependent on the residual stress state in the surface layer. The aim of this paper is to measure the depth profiles of residual stresses in the carburized steels by electronic speckle laser interferometry (ESPI) assisted hole-drilling, and to compare the results with those measured by X-ray diffraction technique. To comprehend the differences in the residual stress state, the low-C steel components were carburized, and then, tempered in the range of 180-600. degrees C. Microstructural investigations and hardness measurements were also conducted. The results obtained from both techniques gave identical results, and showed that the beneficial compressive residual stresses exist at the surface after carburizing, and their magnitudes decrease with increasing tempering temperature. It was concluded that ESPI assisted hole-drilling, with optimized drilling and stress calculation parameters, is suitable for determining the residual stress state of the carburized and tempered steels.

Comparison of Nondesturctive Stress Measurement Techiques for Determinatuion of Residual Stresses in the Heat Treated Steels Hizli, Huseyin; Gür, Cemil Hakan (MATERIALS RESEARCH FORUM LLC, 105 SPRINGDALE LN, MILLERSVILLE, PA 17551 USA; 2018-09-14) 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 of the variations in surface residual stress distributions in the carburized 19CrNi5H steels by means of non-destructive and semi-destructive measurement techniques, Magnetic Barkhausen...
Nondestructive evaluation of the effects of carburizing process parameters on microstructure and residual stress state of SAE 9310 steel via magnetic Barkhausen noise method Yıldırım, Zafer; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2022-2-11) Carburizing is a surface treatment process applied for improving the surface hardness, wear resistance, and also fatigue life of some critical aerospace and automotive components, such as gears, bearings, and bushings. It consists of carbon diffusion into low-C steels in the austenitized condition which results in a carbon gradient along with the depth, then followed by quenching, sub-zero treatment, and tempering. In a carburized component, a strong and wear-resistant surface layer (the case) with compress...
Measurement of residual stresses in the carburized steels by non destructive techniques Hızlı, Hüseyin; Kaleli, Tuğçe; Gür, Cemil Hakan (null; 2016-10-01) Residual stress state on the surface layers has a critical effect on the service performance and fatigue life of the carburized components. Non-destructive determination of residual stress state in a rapid and reliable way has being gained importance for industrial applications. The aim of this study is to investigate the efficiency of the magnetic Barkhausen noise (MBN) method for monitoring the residual stress variations as a function of carburizing process parameters. For this purpose, MBN and XRD measur...
Application of the Contour Method to Determine Axial Residual Stresses in Cold Extruded Steel Rods Aydin, O.; Şimşir, Caner (2021-01-01) Residual stresses in cold extruded parts play an important role in both component lifetime and succeeding in manufacturing performance. When a cold extruded part is used directly, the lifetime of the part depends on the residual stresses induced during cold extrusion. On the other hand, if the part is exposed to post operations such as machining, residual stresses may cause distortions. Despite their importance, there are only a few residual stress measurement methods to assess axial residual stresses in fu...
Evaluation of several multiaxial high cycle fatigue endurance criteria Engin, Zafer; Çöker, Demirkan; Department of Aerospace Engineering (2018) Multiaxial high cycle fatigue is an important failure mode for industrial applications as it is experienced by many engineering parts such as rotor blades and crankshafts. Determining the critical locations and especially the fatigue lives of such components have great importance. Therefore, a methodology is needed which would replace expensive and time-consuming test campaigns as it is not possible and feasible to simulate all the loading scenarios that component would experience during the service life. T...
