Measurement of fine pearlite interlamellar spacing by atomic force microscopy
Journal of Materials Science, 1997Pearlite interlamellar spacing is an important parameter controlling ductility and strain hardening of carbon steels. Fine pearlite is the appropriate initial microstructure for drawing high carbon steel with exponential strain hardening rate, leading to high final tensile strengths. The majority of optical and electron microscopy methods for measuring

Effect of interlamellar spacing of pearlite on the attenuation of ultrasound
NDT International, 1979The attenuation of ultrasound was studied in samples of pearlitic steel taken from railway wheels containing between 0.53 and 0.61% carbon. A strong dependence of ultrasonic attenuation on grain size was observed; in addition a relationship was shown between the interlamellar spacing of pearlite in the steel and the attenuation coefficient.

Effect of alloys additions on the interlamellar spacing of pearlite
Archiv für das Eisenhüttenwesen, 1979The spacing of pearlite was measured to investigate the effect of, alloying elements on this parameter using high purity plain carbon, 2 % Co, 2 % Si, 1 % Cr and 0.3 % Mo eutectoid steels. The investigation revealed that the addition of these alloying elements increases the spacing of pearlite at a given undercooling.

Effect of interlamellar spacing on fracture toughness of nano-structured pearlite
Materials Science and Engineering: A, 2017Abstract Microstructural refinement to the nanoscale imparts tremendous strength to metals while following the Hall-Petch relationship. However, most manufacturing methods to make nanostructured metals are limited by the maximum size of the final product.

Acta Metallurgica, 1980
Abstract A systematic study of the tensile deformation behaviour of a unidirectionally solidified AlCuAl 2 eutectic alloy has been made. High sensitivity tensile tests were performed on alloys with different heat-treatments and interlamellar spacings, λ, and the microstructure of the alloys was examined by transmission electron microscopy in both ...

Interlamellar Spacing in Directionally Solidified Eutectic Thin Films
Metallurgical Transactions A, 1984Fault-free lamellar structures were grown in eutectic thin films of Pb-Sn, Cd-Pb, and Al-Al2Cu. The 2 μ thick films were directionally solidified by either a scanning laser or a quartz iodine lamp. A thermal gradient at the solid-liquid interface was estimated to be 8000°C/cm for the laser heat source compared to 200°C/cm for the lamp.

Effect of cumulative cold drawing on the pearlite interlamellar spacing in eutectoid steel
Scripta Materialia, 1998In this paper an analysis is made of the influence of manufacture by continuous cold drawing on the interlamellar spacing of an eutectoid prestressing steel. Consideration is given to the microstructure evolution as the drawing progresses up to the final commercial product which is heavily drawn and has undergone severe straining.

Superior Sodium Storage of Vanadium Pentoxide Cathode with Controllable Interlamellar Spacing
Electrochimica Acta, 2017Abstract The orthorhombic and hydrated vanadium pentoxide (V 2 O 5 ) films are fabricated via a facile electrodeposition method followed with a controllable annealing process. Served as sodium ion batteries (SIBs) cathode, the hydrated V 2 O 5 film exhibits enhanced sodium storage performance over the orthorhombic V 2 O 5 film, originating from ...

Osmotic effects on the enclosed volume and interlamellar spacing of multilamellar DODAC vesicles
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2008Abstract Dispersions of multilamellar dioctadecyldimethylammonium chloride (DODAC) vesicles are known to have a wide range of sizes and lamellarities. Osmotic effects on these dispersions were investigated by means of NMR diffusometry and small angle X-ray scattering (SAXS).

Monte Carlo simulations of the interlamellar spacing in model n-alkane crystals
The Journal of Chemical Physics, 1998Monte Carlo simulations are carried out on a simple one-dimensional model of n-alkane crystals to investigate the chain length dependence of the interlamellar spacing, which has implications with regard to the Raman spectra of n-alkane crystals. The results of these simulations show no significant chain length dependence for the interlamellar spacing ...
