Abstract

A sintered material suitable for use in making cutting-tools and elements of heat-engines such as turbine blades and jet-propulsion nozzles consists of alumina in a proportion greater than 30 per cent, one or more of the following oxides; iron oxide, chromium oxide, manganese oxide, vanadium oxide and titanium oxide in proportion from 0.05-5 per cent and one or more metals, or alloys consisting of metals of the 6th Group of the Periodic Table and/or from the iron group of the Periodic Table, in a proportion greater than 1.0 per cent. The material may be formed by sintering a mixture of the components, e.g. at a temperature in , the range 1500-1900 DEG C. Alternatively the oxide or oxides other than alumina may be formed from the metal or metals by partial oxidation during the sintering step by action of the sintering furnace atmosphere. The conditions of the sintering step may be such that one or more covalent binary compounds, e.g. chromium nitride, are formed to aid the formation of the metal-to-oxide bond.
