Abstract
A heat-treatable titanium-containing ferrous alloy produced by sintering or infiltration comprises 20-90 per cent by volume of a titanium-base carbide with the balance of the alloy a ferrous matrix which contains at least 60 per cent of iron, the matrix being characterized by a body centred cubic structure at ordinary temperature transformable to a face centred cubic structure at elevated temperature below the melting point of the matrix. The titanium carbide may be partly replaced by one or more of tungsten carbide up to 35 per cent, vanadium carbide up to 35 per cent, zirconium carbide up to 25 per cent, niobium carbide up to 10 per cent and tantalum carbide up to 10 per cent, the total amount of these optional carbides not amounting to more than 50 per cent of the carbides present. The alloy may be heat-treated to give an annealed structure which may contain pearlite, spheroidite or martensitic decomposition products or martensite or bainite. For example the alloy may be heated at a temperature in the range 700 DEG C.-1050 DEG C. for up to 4 hours in a reducing atmosphere containing about 93 per cent nitrogen and 7 per cent hydrogen and then cooled at a rate of under 15 DEG C. per hour to 540 DEG C. or less. In another example the alloy annealed at about 870 DEG C. in a protective atmosphere, then was hardened by austenitizing at about 980 DEG C. and quenched in an oil bath and tempered for 1 hour at about 200 DEG C. Examples of steels which can be used as the ferrous matrix including as alloying constituents chromium, molybdenum, vanadium, tungsten and cobalt are referred to.
