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

Effect of interlamellar spacing on fracture toughness of nano-structured pearlite

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2017
Abstract 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.

Effect of pearlite interlamellar spacing on fatigue property of a wheel steel

Materialwissenschaft Und Werkstofftechnik, 2020
AbstractDifferent 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.

Measurement of the interlamellar spacing of pearlite

Metallography, 1984
Abstract 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

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

Effect of cumulative cold drawing on the pearlite interlamellar spacing in eutectoid steel

Scripta Materialia, 1998
In 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.

Effect of alloys additions on the interlamellar spacing of pearlite

Archiv Für Das Eisenhüttenwesen, 1979
The 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.

Unidirectional transformation of Fe-0.8C-Co alloys: Part I. Process per structure relationships and the significance of pearlite interlamellar spacing measurements

Metallurgical and Materials Transactions A - Physical Metallurgy and Materials Science, 1977
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 ...

Effect of prior austenite grain size and pearlite interlamellar spacing on strength and fracture toughness of a eutectoid rail steel

Materials Science and Technology, 1986
AbstractThe influence of prior austenite grain size dγ, and true interlamellar spacing of pearlite St on the strength and fracture toughness of a eutectoid rail steel has been investigated. Specimens were machined from rail sections and heat treated to produce a wide variation in dγ and st. Mechanical properties studied included 0·2% proof stress σ0·2,
