Evaluation of true interlamellar spacing from microstructural observations [PDF]

open access: yesJournal of Materials Research, 2008
A method for evaluating true interlamellar spacing from micrographs is proposed for a multidomained lamellar structure. The microstructure of these materials is assumed to be composed of many domains with the lamellae aligned roughly parallel to each other within each domain and with the domains themselves randomly oriented relative to one another.

Effect of Interlamellar Spacing on the Monotonic Behavior of C70 Pearlitic Steel [PDF]

open access: yesAdvanced Materials Research, 2014
The effect of interlamellar spacing on monotonic behavior of C70 pearlitic steel was investigated. Tensile tests under X-ray diffraction coupled with self-consistent model have been used to identify the role of interlamellar spacing on the ferrite plasticity parameters and residual stresses.

Effect of the interlamellar spacing on the monotonic and cyclic behavior of C70 pearlitic steel

open access: yes, 2013
L’effet de l’espacement interlamellaire sur le comportement sous chargements monotone et cyclique de l’acier perlitique C70 a été étudié. Une démarche expérimentale conjuguant les essais de traction « in-situ » sous DRX et traction « in-situ » sous MEB couplées à une modélisation auto-cohérente a été adoptée.

Learning style, modal preference & the spacing effect in an online project management training programme. [PDF]

open access: yes
Constant and continued up-grade of skills and qualifications is imperative in a knowledge society (David & Foray 2003, OECD 2007) and central to Continued Professional Development (CPD) programmes in most organisations.

Effect of Cooling Rate on Microstructure and Mechanical Properties in the CGHAZ of Electroslag Welded Pearlitic Rail Steel

open access: yesMetals, 2019
The effect of cooling rate, ranging from 6 to 1 °C/s, on microstructure and mechanical properties in the coarse-grained heat affected zone (CGHAZ) of electroslag welded pearlitic rail steel has been investigated by using confocal scanning laser ...

Consolidation of B4C-TaB2 eutectic composites by spark plasma sintering

open access: yesJournal of Asian Ceramic Societies, 2015
The in situ synthesis/consolidation of B4C-TaB2 eutectic composites by spark plasma sintering (SPS) is reported. The microstructure–property relations were determined for composites with the B4C-TaB2 eutectic composition as functions of TaB2 content, and

Crevice corrosion of U75V high-speed rail steel with varying crevice gap size by in-situ monitoring

open access: yesJournal of Materials Research and Technology, 2022
Crevice corrosion of high-speed rail steel U75V was studied with varying gap size by using self-designed device. Increasing gap size inhibited exterior cathodic reduction reaction of oxygen, inducing decrease of potential difference between interior and ...

Preparation of Composite Hydrogel Based on Polyacrylamide and the Effect of Kaolinite on Its Properties in the Reservoir Conditions [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2013
A gel composite (based on polyacrylamide and crosslinker Cr(III) acetate) was prepared by solvent method (distillate and water formation) and nanoclay particle (kaolinite). Using XRD tests, d001 was evaluated for kaolinite nanoparticles in gel composite.

Microstructure Refinement on Crevice Corrosion of High-Speed Rail Steel U75V Visualized by an In Situ Monitoring System

open access: yesFrontiers in Materials, 2022
Rail foot covered by a fastener will suffer from crevice corrosion, leading to thinning and localized attack of crevice interior posing a risk of failure. This work investigated crevice corrosion behavior of a typical pearlitic high-speed rail steel U75V,
