The static spheroidization of a silicon-containing steel was studied employing quantitative metallography and hardness measurements. Specimens with interlamellar spacings of 0.57 and 0.26μm were annealed at temperatures of 600, 650 and 700° C to obtain the spheroidization of Fe3C. The results of quantitative metallography and hardness measurements indicate that the rate of spheroidization is controlled by the diffusion of iron at the Fe-Fe3C interface. The increase in the rate of spheroidization due to a reduction in the interlamellar spacing is thought to be caused by an increase in the defect density in the Fe3C plates when pearlite has a smaller interlamellar spacing.

CRACK-GROWTH KINETICS OF 7050-T73651 ALUMINUM-ALLOY UNDER CONSTANT LOAD AT 150-DEGREES-C SARIOGLU, F; ABACHI, P; DORUK, M (Springer Science and Business Media LLC, 1993-03-15) Crack growth tests at 150-degrees-C under constant load conditions were performed on compact tension specimens of 7050-T73651 aluminium alloy. The d.c. potential drop method was employed to monitor crack lengths throughout the tests. Fracture mechanics parameters such as the stress intensity factor (K) and energy-rate line integral (C*) were used to establish correlation with the crack propagation rates. As a result of experiments it was found that crack growth rates (da/dt) versus K, over discrete ranges o...
Hot-pressed hydroxylapatite/monoclinic zirconia composites with improved mechanical properties Evis, Zafer (Springer Science and Business Media LLC, 2007-04-01) Composites of hydroxylapatite (HA) and monoclinic zirconia were hot-pressed at 1100 degrees C and 1200 degrees C under vacuum to study the phase transformations and the mechanical properties. X-ray diffraction results showed a higher phase transformation from monoclinic-ZrO2 to tetragonal-ZrO2 when the sintering temperature increased from 1100 degrees C to 1200 degrees C. HA decomposed faster when the amount of ZrO2 in the composites increased. Moreover, small amount of alpha-TCP and CaZrO3 was observed in ...
Plastic deformation induced microstructure evolution through gradient enhanced crystal plasticity based on a non-convex Helmholtz energy Klusemann, Benjamin; Yalçınkaya, Tuncay (Elsevier BV, 2013-09-01) A gradient crystal plasticity model in the framework of continuum thermodynamics and rate variational formulation is presented for the description of plastic deformation patterning in a system with non-convex energetic hardening. The paper focuses on the extension of the 1D deformation patterning analysis of Yalcinkaya et al. (2011) to 2D for monotonic loading histories. Solution algorithm is based on the simultaneous solution of displacement and plastic slip fields, which have been considered as primary va...
Plane strain analytical solutions for a functionally graded elastic-plastic pressurized tube Eraslan, Ahmet Nedim (Elsevier BV, 2006-09-01) Plane strain analytical solutions to functionally graded elastic and elastic-plastic pressurized tube problems are obtained in the framework of small deformation theory. The modulus of elasticity and the uniaxial yield limit of the tube material are assumed to vary radially according to two parametric parabolic forms. The analytical plastic model is based on Tresca's yield criterion, its associated flow rule and ideally plastic material behaviour. Elastic, partially plastic and fully plastic stress states a...
Sintering and humidity-sensitive behaviour of the ZnCr2O4-K2CrO4 ceramic system Bayhan, M; Hashemi, T; Brinkman, AW (Springer Science and Business Media LLC, 1997-12-15) Solid state reaction at elevated temperatures and the sintering behaviour of zinc chromite formed by zinc oxide and chromite oxide were investigated. Crystalline structure, surface and fractured morphologies and humidity-sensitivity characteristics of ZnCr2O4-K2CrO4-CuO were studied. The fired ceramic body, which proved to be mainly constructed from ZnCr2O4 spinel grains, was porous. The humidity characteristics of the sensor showed that the resistance decreased as a logarithmic function with an increase in...
