Measurement of pearlite interlamellar spacing in hypereutectoid steels

Materials Characterization, 2005
In hypereutectoid steels, determination of interlamellar spacing is essential to microstructural characterization, since both static and dynamic properties have been related to the pearlitic structure. Generally, quantitative analysis of the size of a pearlite colony and its interlamellar spacing is performed using optical and electron microscopy ...

Effect of interlamellar spacing on the mechanical properties of 0.65% C steel

Materials Characterization, 2001
The mechanical properties of a steel containing a nearly fully pearlitic structure have been examined as a function of the interlamellar spacing. The steel had been heat-treated at different austenitization temperatures in order to obtain varying interlamellar spacings.

Application of the Disector to Determine the Distribution of True Interlamellar Spacing in Lamellar Microstructures

Practical Metallography, 2010
Abstract It is well known that the interlamellar spacing controls the mechanical properties of any material with a lamellar microstructure. It is also expected, although not yet established, that varying distribution of interlamellar spacing would also influence the properties.

Controlling Interlamellar Spacing in Periodically Grafted Amphiphilic Copolymers

Macromolecules, 2016
We have examined a series of periodically grafted amphiphilic copolymers (PGACs) wherein pendant MPEG segments of varying lengths (TREG, 350, 550, and 750) were grafted at periodic intervals along a long crystallizable alkylene (C-20) backbone. The immiscibility of the alkylene and PEG segments, and the strong propensity of the alkylene segments to ...

The Interlamellar Spacing of Pearlite

Praktische Metallographie/Practical Metallography, 2015
Abstract The interlamellar spacing of pearlite is a very important microstructural parameter for steels containing pearlite, and becomes more important as the pearlite content increases towards a fully pearlitic microstructure. As the amount of pearlite in ferrite-pearlite microstructures increases, so does the strength, but toughness

Calculation models of interlamellar spacing of pearlite in high-speed 82B rod

Journal of Iron and Steel Research International, 2008
With the investigated subject of 82B rod, the interlamellar spacings of pearlite at different isothermal transformation temperatures and different cooling rates during continuous cooling transformation were measured, and the effect of the isothermal transformation temperature and cooling rate on the interlamellar spacing was analyzed quantitatively ...

Interlamellar spacing measurements in the Sn-Pb and Al-CuAl2 Eutectic Systems

Metallurgical and Materials Transactions A - Physical Metallurgy and Materials Science, 1976
Measurements of the variation of interlamellar spacing with composition are presented for the Sn-Pb and Al-CuAl2 eutectics. The interlamellar spacing in both systems was only slightly dependent on composition. This is contrary to the previous findings of Jordan and Hunt who found a marked variation of λ2υ with composition in the Al-CuAl2 system ...

The Optimization of Interlamellar Spacing in a Nanopearlitic Lead-Patented Hypoeutectoid Steel Wire

Journal of Materials Engineering and Performance, 2011
In this study, in order to optimize the interlamellar spacing prior to drawing operation in a nanopearlitic lead patented hypoeutectoid steel wire, a model based on finite element method is presented to predict the optimum immersion time in a lead bath. A typical suitable immersion time for the wire with 1.8 mm diameter is about 10 s. The austenitizing

Prediction of interlamellar pearlite spacing of tyre bead wires after patenting using electromagnetic techniques

Insight: Non-Destructive Testing and Condition Monitoring, 2013
An attempt has been made to correlate interlamellar pearlite spacing with electromagnetic parameters after the patenting stage (Ø3.1 mm wire) on a tyre bead wire line. Two different techniques were adopted for the above work.

Effect of interlamellar spacing on the elastoplastic behavior of C70 pearlitic steel: Experimental results and self-consistent modeling [PDF]

Materials & Design, 2014
The effect of pearlite microstructure characteristics on strength and deformation 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 ...
