Numerical simulation of solidification kinetics in A356/SiCp composites for assessment of as-cast particle distribution

Kalkanlı, Ali
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 to predict the local microstructural scales and to evaluate the risk of cluster formation in cast particle reinforced composites.


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...

Modelling and Monte Carlo simulation of the atomic ordering processes in Ni3Al intermetallics
Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (IOP Publishing, 2007-03-01)
The evolution of atomic ordering processes in Ni3Al has been modelled by a Monte Carlo ( MC) simulation method combined with the electronic theory of alloys in pseudopotential approximation. The magnitudes of atomic ordering energies of atomic pairs in the Ni3Al system have been calculated by means of electronic theory in pseudopotential approximation up to the 4th coordination spheres and subsequently used as input data for MC simulation for more detailed analysis for the first time. The Bragg - Williams l...
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...
3D FEM simulation of steel quenching and investigation of the effect of asymmetric geometry on residual stress distribution
Simsir, Caner; Gür, Cemil Hakan (Elsevier BV, 2008-10-16)
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...
