ABSTRACT:
A class of iron base materials which derive improved properties from the presence of a finely dispersed titanium diboride phase is described. The materials comprise a ferrous matrix containing a fine relatively uniform dispersion of titanium diboride particles are typically less than 0.1 micron in diameter and are present in number densities of 10.sup.10 per mm.sup.3 or greater. These materials are produced by the rapid solidification of an iron alloy containing titanium and boron. Powder metallurgy techniques may be employed.
