Title:
PRODUCTION OF IRON DISILICIDE
Document Type and Number:
Japanese Patent JPH0920512
Kind Code:
A
Abstract:
PURPOSE: To remarkably improve the production efficiency due to no need of high-temperature melting and sufficient heat treatment at a relatively low temperature and in a short time.
CONSTITUTION: A raw material is prepared so as to provide 1:>2.0 and 1:≤3.0 atomic ratio Fe:Si of iron to silicon contained in a raw material powder and the mechanical alloying is carried out until the iron in the raw material is consumed to ≤20% in a method for producing a β-phase iron disilicide comprising mechanically alloying iron and silicon and then heat-treating the resultant alloy. Thereby, the α- and -phase iron silicides are produced and subsequently heat-treated.
