During quench hardening of steel components, obtaining the desired distribution of microstructure and residual stresses with minimum distortion is essential in order to achieve production goals and reliable service performance. In this study, a 3D FEM based model, which is integrated into commercial FEA software Msc.Marc (R) via user subroutines, has been developed to predict temperature history, evolution of microstructure and internal stresses during quenching. For experimental verification, eccentrically drilled C60 steel cylinders were quenched from 830 degrees C into water at 20 degrees C. The results indicate that the model can effectively predict the trends in the distribution of residual stresses for 3D asymmetric components.

Sheet metal forming analyses with an emphasis on the springback deformation FIRAT, MEHMET; Kaftanoglu, Bilgin; Eser, Orhan (Elsevier BV, 2008-01-21) An accurate modeling of the sheet metal deformations including the springback is one of the key factors in the efficient utilization of FE process simulation in the industrial setting. In this paper, a rate-independent anisotropic plasticity model accounting the Bauschinger effect is presented and applied in the FE forming and springback analyses. The proposed model uses the Hill's quadratic yield function in the description of the anisotropic yield loci of planar and transversely anisotropic sheets. The ma...
Numerical simulation of solidification kinetics in A356/SiCp composites for assessment of as-cast particle distribution CETIN, Arda; Kalkanlı, Ali (Elsevier BV, 2009-06-01) The present work is aimed at studying the effect of solidification rate on reinforcement clustering in particle reinforced metal matrix composites (PMMCs) through numerical simulations and experimental studies. A macrotransport-solidification kinetics (MTSK) model was used to simulate the solidification kinetics of the PMMCs. The experimental validation of the numerical model was achieved through the Newtonian and Fourier thermal analysis methods. Results reveal that the MTSK model can be successfully used ...
Generalized transient temperature behavior in induction heated workpieces OKMAN, Oya; Dursunkaya, Zafer; Tekkaya, A. Erman (Elsevier BV, 2009-09-19) Electromagnetic-thermal coupled numerical analysis of induction heating is time intensive if three-dimensional models are used. In this study, by processing the results of finite element computations, a dimensional analysis is carried out to predict the transient temperature rise time at the surface of an induction heated workpiece. A unique set of curves is found that describes the transient dimensionless temperature at a point on the surface as a function of the electromagnetic skin depth alone. The effec...
Control of the thickness distribution of evaporated functional electroceramic NTC thermistor thin films Schmidt, R.; Parlak, Mehmet; Brinkman, Am (Elsevier BV, 2008-04-01) In this work the thickness distribution of NTC thermistor thin films produced by low deposition rate (0.8 nm s(-1)) electron-beam evaporation is investigated. The target preparation, deposition conditions and geometrical set-up of the evaporation mechanism are described in detail. The evaporation geometry is shown to be critical for the thickness distribution of evaporated films. The film thickness distribution of evaporated layers was measured across a macroscopic film surface using Alpha Step stylus profi...
Effect of solidification rate on spatial distribution of SiC particles in A356 alloy composites CETIN, Arda; Kalkanlı, Ali (Elsevier BV, 2008-08-26) The damage and deformation behaviour of particulate reinforced metal matrix composites (PMMCs) can be highly sensitive to local variations in spatial distribution of reinforcement particles, which markedly depend on melt processing and solidification stages during production of PMMCs. The present paper attempts to study the effect of solidification rate on cluster formation in an Al-Si-Mg (A356) alloy composite reinforced with SiC particles and to explore the applicability of spatial functions to PMMC micro...
