Optimization and control of the microstructure is important for improving the properties of steel components. Development of non-destructive techniques for microstructure characterization is a critical task. Magnetic Barkhausen Noise (MBN) technique is a promising and challenging non-destructive technique for automated evaluation of microstructures in steel components in a fast and reliable manner. This paper presents the results of MBN measurements for microstructure characterization of the quenched and tempered steels.

Characterization of steel microstructures by magnetic barkhausen noise technique
Gür, Cemil Hakan (2012-12-01)
Optimization and control of the microstructure is vital for improving performance and service life of the steel components. Development of non-destructive techniques for microstructure characterization has been a challenging task for many years. Magnetic Barkhausen Noise method is a non-destructive evaluation technique with high potential for characterization of steels. This paper summarizes the related studies performed at METU.
Nondestructive Monitoring of Pearlite Degradation in Medium Carbon Steels by Magnetic Barkhausen Noise Method
Gür, Cemil Hakan (2017-09-06)
Cementite in steel microstructures exits in various forms such as lamellae in pearlite after normalizing, or nano-size particles in ferrite matrix after quenching-tempering, or large spheroidal particles in ferrite matrix after spheroidizing heat treatment. Any alteration in the cementite morphology influences the strength and hardness of pearlite that exists in most of the steel structures used in wide range of industrial applications. For instance, spheroidizing heat treatment is intentionally applied to ...
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...
Microstructure characterization of heat-treated ferromagnetic steels by magnetic barkhausen noise method
Gür, Cemil Hakan (2019-01-01)
This paper presents non-destructive evaluation of microstructures of heat treated steels by the Magnetic Barkhausen Noise (MBN) method. Various steel specimens having different microstructures were produced by appropriate heat treatments. All specimens were characterized by metallographic examinations, hardness and MBN measurements. The results showed that MBN parameters are highly sensitive to the variations in the microstructure, and this method is a promising candidate for practical non-destructive chara...
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...
