Lanthanum - Less Common Metals
LaFeSi: LaFeSi is a cast product containing lanthanum (La), iron (Fe), and silicon (Si). It represents an alloy where lanthanum, iron, and silicon atoms are combined, potentially forming a solid solution or intermetallic compounds. The properties of LaFeSi would depend on the specific composition and the ratio of the different elements. LaNi ...
Lanthanum is a useful element for the promotion of a high nodule count in nodular iron, which in combination with controlled rates of graphitisation will help to reduce the occurrence of micro porosity. It is more effective when incorporated as an inoculant, preferably as …
Ferrocerium - Wikipedia
Ferrocerium (also known in Europe as Auermetall) is a synthetic pyrophoric alloy of mischmetal (cerium, lanthanum, neodymium, other trace lanthanides and some iron – about 95% lanthanides and 5% iron) hardened by blending in oxides of iron and/or magnesium.
Lanthanum - Wikipedia
Lanthanum is the first element and prototype of the lanthanide series. In the periodic table, it appears to the right of the alkaline earth metal barium and to the left of the lanthanide cerium. Lanthanum is generally considered the first of the f-block elements by …

Lanthanum containing MgFeSi has been used in ductile iron production for 40 years. First solely for "in the mould" processes, and then in the last 12 years it has seen increased use as a ladle alloy. There are several reasons why these alloys have gained popularity, such as shrinkage reduction, improved microstructure properties, and a lower ...
Lanthanum Role in the Graphite Formation in Gray Cast Irons
Dec 21, 2020 · La has limited but specific benefits at 0.05–0.06%S irons, including favorable graphitizing factors (a higher amount of graphite precipitated at the end of solidification), lower eutectic...
Lanthanum - ScienceDirect
Jan 1, 2022 · Lanthanum is added in small quantities to aluminum, iron, steel, or other host metals to improve the selected physical properties of the resulting alloys. La is added as a ferroalloy, master alloy, mischmetal (a mix of mostly cerium and …
