Measurement of pearlite interlamellar spacing in hypereutectoid steels
Materials Characterization, 2005In 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 pearlite interlamellar spacing on fatigue property of a wheel steel
Materialwissenschaft Und Werkstofftechnik, 2020AbstractDifferent pearlite interlamellar spacings of 0.54 % carbon (C) wheel steel were obtained by heat treatment, and the influence of interlamellar spacing on fatigue behavior of the steel was studied through conducting the staircase method fatigue testing and decreasing/increasing stress intensity factor range (ΔK) fatigue crack growth tests.

A Review of the Data on the Interlamellar Spacing of Pearlite
Metallurgical and Materials Transactions A: Physical Metallurgy and Materials Science, 1984After defining interlamellar spacing the various optical and electron optical methods for measuring spacing are outlined. It is clear for both isothermal and forced velocity transformation conditions that pearlite can grow at a constant velocity with a range of true spacings.

Measurement of the interlamellar spacing of pearlite
Metallography, 1984Abstract Following a historical review of methods that have been employed for measuring the interlamellar spacing of pearlite, these methods are compared with reference to a continously cooled AISI 1040 carbon steel specimen. Extensive analyses, using TEM thin foils and stereological analysis of TEM replicas, were conducted to determine the mean true

Calculation models of interlamellar spacing of pearlite in high-speed 82B rod
Journal of Iron and Steel Research International, 2008With 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 ...

Effect of interlamellar spacing on fracture toughness of nano-structured pearlite
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 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.

The Interlamellar Spacing of Pearlite
Praktische Metallographie/Practical Metallography, 2015Abstract 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

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.

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. One was electromagnetic sorting and the other was measurement of the inductance of a suitable electromagnetic encircling coil at

Fe-0.8C-Co alloys have been unidirectionally transformed by translation through a temperature gradient which establishes a single interface between the austenite and pearlite phases. A comparison between the temperature gradient calculated to maintain a single planar interface by preventing nucleation ahead of the interface and that actually required ...
