Pearlite is a lamellar product of eutectoid decomposition, which may form in steels and non-ferrous alloys during transformations under isothermal or continuous-cooling (1,2). A pearlite nodule is composed of multiple colonies; each colony has parallel lamellae, which are orientated differently with respect to lamellae in adjacent colonies. This also exhibits a wide range of interlamellar spaci...

the effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. in this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. the results were the minimum interlamellar spacing of 35 nm and maximum ulti...

The effect of an addition of 0.37 Wt % Won the overall transformation rate of the austenitepearlite reaction in a eutectoid steel is examined. Pearlite growth rates and interlamerllar spacing are measured as a function of transformation temperatures. Tungesten raises the Ael temperature, for most transformation temperatures, decreases the overall reaction rate, the growth rate and the interlame...

Abstract The effect of cobalt and aluminium on the austenite-to-pearlite transformation in a super-bainitic steel was investigated. The experimental work s...

Swedish truck industry is investigating the possibility for implementing the use of Compacted Graphite Iron (CGI) in their heavy duty diesel engines. Compared to the alloyed gray iron used today, CGI has superior mechanical properties but not as good machinability. Another issue that needs to be addressed when implementing CGI is the inhomogeneous microstructure when the cast component has diff...

The pearlite lamellar spacing (λpearlite) is one of the microstructure parameters that define strength graphite iron (LGI). transformation kinetics λpearlite has been subject several modeling studies for steels, which demonstrated can be calculated as a function undercooling. However, it hard to find in literature models prediction LGI. In present work, fully pearlitic LGI was investigated wi...

High-carbon steels have been used to high-strength steel wire and strands for prestressing concrete. The necessity of levels at increasingly larger diameters rods is a technological challenge. Two with without Nb were obtained in mill, submitted detailed microstructural (previous austenitic grain size, pearlite interlamellar spacing colony size) mechanical characterization through tensile tests...

A model that describes pearlite-to-austenite transformation during continuous heating in a eutectoid steel has been developed. The influence of structure parameters, such as interlamellar spacing and edge length of pearlite colonies, and heating rate on the austenite formation kinetics has been experimentally studied and considered in the modeling. It has been found that the kinetics of austeni...
