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 ...

This study investigates how tramp elements from increased scrap usage influence phase transformations in low‐alloyed steel. Combining dilatometry and microscopy reveal that tramp elements delay transformations, reduce critical cooling rates and increase hardenability.

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling
Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

A robust computational framework is proposed, which is designed to simulate microstructural‐scale plastic deformation and damage in pearlitic steels. The framework is calibrated and validated using experimental data from pearlitic steel rail samples. Subsequently, it is employed to investigate the impact of microstructural parameters, such as cementite

Experimental research on the effect of induction reheating on the microstructure and mechanical properties of hot-rolled low-alloy steel plate [PDF]
Electric induction reheating is used to control the temperature of hot-rolled steel products. To investigate the effect of this on microstructure and mechanical properties, hot-rolled low-alloy steel plate was cooled, reheated, and then either quenched ...

An arc welding process for long butt joint of high carbon −75Mn steel plates without preheating was selected, assuring quality of weld and productivity. Abstract In order to ensure the stability of the track mechanical device, this paper solves the problem of attaching the lock flange to the side of the rail.

Application of the diffusion equation to modeling phase transformation during cooling of pearlitic steel [PDF]
Exploitation properties of rails are formed by controlled heat treatment of the head of the rail carried out after rolling. Complex cooling schedules have to be applied to obtain required microstructure and properties of rail steels.

Modelling of isothermal formation of pearlite and subsequent reaustenitisation in eutectoid steel during continuous heating [PDF]
Three different morphologies of pearlite have been formed isothermally at three different temperatures in a eutectoid steel. Moreover, the interlamellar spacing of the pearlite was calculated using the Zener and Hillert theoretical method.

Taking advantage of co‐deformation mechanisms is a promising way to achieve fine grain metal matrix composites or architectured structures with unique properties. Understanding physical mechanisms is critical to promote refinement or fragmentation or mechanical mixing.

Eutectoid steels present a wide range of interesting mechanical properties (high strength, wear resistance, ductility and toughness) and could be a cheaper alternative to high strength low-alloyed steels (HSLA) in applications where weldability is not a ...
