Microstructural characterization of hypoeutectoid steels quenched from the Ae1 - Ae3 intercritical temperature range by magnetic barkhausen noise technique
Boyacıoğlu, Beril; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2006)
This thesis aims to examine the possibility of using Magnetic Barkhausen Noise technique in characterizing the ferritic-martensitic microstructure of hypoeutectoid steels quenched from the intercritical temperature range. For this purpose, rectangular specimens were prepared from SAE 1020, 1040 and 1060 steels. The specimens were heated at different temperatures within the intercritical temperature range and then quenched into water. Microstructures of the specimens were characterized by metallographic exam...
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...

Peridynamic modeling of wrinkling in a graphene layer
Diyaroglu, C.; Behera, D.; Madenci, E.; Kaya, Yasemin; Kedziora, G.S.; Nepal, D. (2019-01-01)
© 2019, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.This study presents a peridynamic (PD) model of a graphene layer with tension and bending moduli comparable with atomistic simulations as well as experimental findings. After determining the PD in-plane and interlayer bond constants, the PD model is verified against a molecular dynamic simulation of wrinkling in a graphene layer suspended over a trench. Also, the numerical results demonstrate the modeling of a graphene...
Microstructures and phase selection in rapidly solidified Zn-Mg alloys
Akdeniz, Mahmut Vedat (1996-01-15)
The Zn-Mg system has potential glass-forming ability, and therefore studies were made of rapidly solidified zinc-based Zn-Mg alloys containing up to 6 wt % Mg. These alloys exhibited interesting eutectic phase selections and structural transitions across the ribbon thickness which are represented on a microstructure selection diagram for rapid solidification conditions. Although rapid solidification is known in many cases to produce metastable phases, in this case the equilibrium eutectic mixtures of Zn-Mg2...
