Cast Irons Containing Rare Earths

Rare earth additions should not be employed when producing high Nickel containing cast irons (Ni-Resist) due to risk of chunk graphite. The choice of inoculant needs to be considered. For example, Strontium based inoculants are neutralised by rare earths, reducing their effectiveness. The rare earths are susceptible to solute segregation.

appreciably enhanced with alloyed irons. However, since cast irons contain more than 2% carbon, 1 to 3% silicon and up to 1% manganese, their weldability is poor. As cast irons are relatively inexpensive, very easily cast into complex shapes and readily machined, they are an important engineering and structural group of materials.
