This paper presents an evaluation of Cr and Mo influence in solidification and shrinkage defects in grey cast iron. A series of five grey cast irons were produced with different Cr and Mo additions. A test casting was ...

The world rare earth elements [REE] crisis will continue at least in the short and medium term. With less REE available, their future use in foundry alloys should be carefully thought out and other inoculation methods need ...

The development of high-performing components is crucial in applications such as heavy vehicle automotive powertrains. In these applications, strength, weight and thermal conductivity is essential properties. Key materials ...

The problem described in the paper concerns the thermo-physical properties of the green mould material to which the cast iron most often is poured (about 50% of production). The study described in the paper includes the ...

This work deals with the problem of casting production regarding composed castings for rolls, also called gradient castings. The technology of production is a combination of the horizontal centrifugal casting of alloyed ...

Changes in the form and dimensions of ductile iron parts occur during the austempering process, and this poses a challenge whenever tight tolerances need to be satisfied. Thus, it is important to be able to predict the ...

Castings are produced by a manufacturing method which gives the components properties that are depending on design, metallurgy and casting method. The aim is to explore and model the local properties in a cast iron component ...

A commercial ductile iron alloy was submitted to Quenching and Partitioning (Q&P) process. Samples were austenitized at 900ºC for two hours, quenched at 170ºC and held at this temperature for 2 minutes and finally were ...

This work focuses on the study of the solidification macrostructure of compacted graphite iron and its relationship with shrinkage porosity formation. Cast samples especially developed to present shrinkage porosity were ...

In the last three decades, the revolutionary material; the austempered ductile iron (ADI) with its unique combination of mechanical properties, has been offering the design engineer alternatives to conventional material ...
