In this study the as-cast macro and microstructures of medium C – high Si cast steels of three different levels of alloying are characterised. The application of a colour-etching reagent sensitive to Si segregation effectively ...

A high silicon cast steel was studied in the as-cast condition in order to characterise its solidification macrostructure and microsegregation. The steel, poured into 32 mm-keel-block-shaped moulds, has a coarse solidification ...

Casting processes show some weaknesses. A particular problem is presented when the workpiece needs to be subjected to heat treatments to achieve a desired microstructure. This problem arises from the microsegregation ...

Microsegregations of alloying elements developed during solidification are known to affect solid state transformations in spheroidal graphite cast irons. However, no clear relation between them and the presence and extension ...

The aim of this investigation is to characterize the mechanical properties at the microstructural level in ferritic ductile iron. The analysis involves microstructural characterization, nanoindentation testing, atomic force ...

This investigation examines the growth of ferrite during the cooling of spheroidal graphite cast irons through the ferrite-austenite-graphite phase field as conditioned by the partitioning of Silicon. Two different melts ...

This study investigates the effect of chemical composition and microsegregation on the bainitic transformation of high Si cast steels at two different austempering temperatures. The advance of the bainite precipitation as ...
