This study aims to characterise as-quenched and tempered steels by the Magnetic Barkhausen Noise method, and to contribute to optimisation of heat treatment processes. Identical austenitisation and quenching procedures were applied to SAE 1040 and SAE 4140 specimens to eliminate the effect of grain size. Samples were tempered at 200°C and 600°C for 2 hours. Microstructures were characterised by metallographic examinations and hardness measurements. Amplitude, position and frequency spectrum of signals were evaluated using a commercial system. As the tempering temperature increases, in contrast to the reduction in hardness, magnetic response increases due to the enhancement of domain wall displacement.

Simulation of equal channel angular pressing applied to produce structures with ultrafine-sized grains Karpuz, Pinar; Şimşir, Caner; Gür, Cemil Hakan (Inderscience Publishers, 2009-01-01) Severe plastic deformation methods are of great interest in industrial forming applications, as they give rise to significant refinement in microstructures and improvements in mechanical and physical properties. In the 'equal channel angular pressing (ECAP)', which is the most common method for production of ultrafine grained bulk samples, very high plastic strains are introduced into the bulk material without any change in cross section. In this study, the plastic deformation behaviour of the materials sub...
Analysis and calculation of the magnetization, magnetic susceptibility and the specific heat close to phase transitions in heterometallics Dugan, E. Kilit; Yurtseven, Hasan Hamit (Elsevier BV, 2019-10-01) The temperature dependence of the magnetization for DMFeNi and DMFeCu is calculated by the molecular field theory and it is also analyzed as functions of temperature and the magnetic field by the power-law formulae close to the phase transitions in these compounds by using the observed data from the literature. From the analysis, values of the critical exponents beta (temperature-induced order parameter at H = 100 Oe) and delta (field-induced order parameter at T = 2 K) are deduced. Also, using the observed...
A new framework for simulation of heat treatments Şimşir, Caner; Gür, Cemil Hakan (Inderscience Publishers, 2010-12-01) In this study, a mathematical framework based on finite element method (FEM) capable of predicting temperature history, evolution of phases and internal stresses during thermal treatment of metals and alloys was developed. The model was integrated into the commercial FEA software MSC.Marc® by user subroutines. The accuracy of the model was verified by simulating the quenching of eccentrically drilled steel cylinders. Simulation results were justified via SEM observations and XRD residual stress measurements.
Resonance-Based Temperature Sensors using a Wafer Level Vacuum Packaged SOI MEMS Process Aydın, Gülşah Demirhan; Akın, Tayfun (VBRI Press AB, 2020-01-01) This paper reports the development of resonance-based temperature sensors using a wafer level vacuum packaged SOI MEMS process which is normally used to implement various MEMS sensors, including MEMS gyroscopes and accelerometers. Implementing MEMS temperature sensors in such a MEMS process together with sensitive MEMS sensors allows obtaining temperature data, which is very useful for the compensation of a number of parameters of these MEMS sensors for obtaining improved performance from these sensors.

Advances in protective layer-coating on metal nanowires with enhanced stability and their applications Bang, Junhyuk; Coşkun, Şahin; Pyun, Kyung Rok; Doğanay, Doğa; Tunca, Sensu; Koylan, Serkan; Kim, Dongkwan; Ünalan, Hüsnü Emrah; Ko, Seung Hwan (Elsevier BV, 2021-03-01) © 2020 Elsevier LtdThe demand for flexibility in transparent conductive electrodes(TCEs) is increasing due to the functionality demand and convenience of deformable electrodes. The high-cost and brittleness of the conventional indium tim oxide (ITO) films are obstacles to their utilization in TCEs. Metal nanowires are highly promising as substitutes for ITO. Metal nanowire electrodes achieved high-conductivity, high-transparency, and high-stretchability through the development of fabrication technology. Nev...
