Fillet rolling process is an effective method used to improve the fatigue performance of crankshafts by hardening the fillet region and inducing compressive residual stresses. This paper summarizes the work conducted to investigate the effect of rolling load on fatigue behaviour of a micro-alloy steel crankshaft used in diesel engine applications. Based on the staircase test methodology, component-scale resonant bending fatigue tests were conducted to obtain stress versus number of cycles curves and to evaluate the fatigue endurance limits of the crankshaft at un-rolled condition and fillet-rolled conditions at three different loads. Test data was analysed by Dixon-Mood method to calculate the endurance limits. Results showed that the endurance limit increased significantly with fillet rolling process in comparison to un-rolled condition. Endurance limit further increased with the increasing rolling load however with a limited extent above which excessive hardening deteriorates the fillet region; that is the workability limit. The outcomes of this study has shed light on the fillet rolling process to select the optimum rolling load for the used design and material conditions.

Effect of parallel and antiparallel configuration on magnetic damping in Co/Ag/Co/Gd Demirtas, S.; Salamon, M. B.; Koymen, A. R. (AIP Publishing, 2011-06-01) When two ferromagnetic layers have a common resonance frequency, the usual spin-pumping broadening may be reduced by dynamic exchange coupling. Utilizing the antiferromagnetic coupling between Co and Gd, we explore the change in ferromagnetic resonance accompanying a spontaneous transition from parallel to antiparallel magnetic alignment of two Co films below the compensation temperature T-comp. Above T-comp, the data are consistent with conventional models. However, a rapid doubling of magnetic damping acc...
Effects of Nanoparticle Geometry and Temperature on the Structural Evolution in FeCo Nanoalloys Yalçın, Mehtap; Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (Institute of Physics, Polish Academy of Sciences, 2014-02-01) Effects of nanoparticle size (2.0-6.0 rim) and shape (spherical and cubic) on structural characteristic of atomic ordering processes and order-disorder transformation in B2-type ordered equiatomic-FeCo nanoalloys have been studied by combining electronic theory of alloys in the pseudopotential approximation with Ising-type Hamiltonian site exchange Monte Carlo simulation method. Structural evolutions in amorphous nanopaxticles (2-6 nm) of Fe50Co50 alloy have been utilized via molecular dynamic simulations f...
Constraining Gluon Distributions in Nuclei Using Dijets in Proton-Proton and Proton-Lead Collisions at root s(NN)=5.02 TeV Sirunyan, A. M.; et. al. (American Physical Society (APS), 2018-08-01) The pseudorapidity distributions of dijets as functions of their average transverse momentum (p(T)(ave)) are measured in proton-lead (pPb) and proton-proton (pp) collisions. The data samples were collected by the CMS experiment at the CERN LHC, at a nucleon-nucleon center-of-mass energy of 5.02 TeV. A significant modification of the pPb spectra with respect to the pp spectra is observed in all p(T)(ave) intervals investigated. The ratios of the pPb and pp distributions are compared to next-to-leading order ...
A Material Perspective on Consequence of Deformation Heating During Stamping of DP Steels ŞİMŞİR, CANER; Cetin, B.; Efe, Mert; Davut, K.; Bayramin, B. (2017-07-06) Recent studies showed that, during stamping of high strength steels at industrially relevant production rates, local temperature in the blank may rise up to 200°C – 300°C due to deformation heating. Moreover, die temperature may also rise up to 100°C – 150°C for progressive stamping dies. Based on the common assumption that the blank softens as the temperature increases, thermal softening creates a margin in Forming Limit Diagram (FLD) and therefore the FLD determined at room temperature can safely be used ...
Effect of Thickness on Magnetic Properties of Fe36Co36B19.2Si4.8Mo2W2 Thin Film Prepared by Thermionic Vacuum Arc Perincek, F.; Erturk, K.; AYKOL, M.; Kucuk, I.; Akdeniz, Mahmut Vedat (Institute of Physics, Polish Academy of Sciences, 2012-01-01) Fe36Co36B19.2Si4.8Mo2W2 amorphous thin films have been produced by thermionic vacuum arc with thickness varying from 200 nm to 260 mn. X-ray diffraction has been employed to reveal a predominant amorphous phase in the as-prepared samples, although a small crystalline fraction cannot be excluded. The bulk magnetic properties of thin films were examined at room temperature using an ADE Magnetics EV9 vibrating sample magnetometer with maximum magnetic field strength of 1750 kA/m, real-time field control and dy...
