Abstract
A hard refractory body for tool tips or the like consists of a combination of a ternary boride selected from Mo2NiB2 and Mo2CoB2 together with Mo2B and a balance consisting essentially of a solidified phase of at least two of the ingredients of the said ternary boride and diboride, the three phases being present in proportions corresponding to those obtained by forming the body from 15-60 atomic per cent B, 30-70 atomic per cent Mo and 1-40 atomic per cent Ni or Co. The body may be formed of a mixture of 75-25 per cent of the ternary boride and 25-75 per cent of the diboride which is compacted and heated in a protective atmosphere in the range 1500-1800 DEG C. at which temperature a liquid eutectic phase is formed, the liquid phase then being solidified.
