The abrasion wear resistance of irons may be improved by the incorporation of an extra phase to the matrix, typically consistent of carbides. Nevertheless, the improvement in wear resistance is generally accompanied by a ...

Just like other properties, wear resistance is entirely dependent on materials microstructure, which, in turn, is related to the chemical composition and solidification rate that controls phases type, size, amount and ...

This investigation focuses on the study of the dissolution by annealing of carbides present in thin walled ductile iron parts. Ledeburitic carbides are usually present in the microstructure as a consequence of the rapid ...

The present work has investigated the feasibility of achieving carbide free microstructures in low alloy thin wall ductile iron (TWDI) after dissolution heat treatments. Studies were conducted using low alloy and unalloyed ...

This work analyses the secondary carbides precipitation during the destabilization of a 17%Cr white iron containing 195 ppm Boron. The experimental iron was characterized in the as-cast conditions to have comparable ...

Austempered ductile iron (ADI) has a good combination of mechanical properties and castability allowing it to replace forged steels while offering lower costs. CADI is thought to improve ADI's abrasion resistance by the ...
