A method of manufacturing a composite material, wherein the composite material comprises:
- (a) a compound of formula (W1-xMxXy)n,
- wherein:
- W is tungsten (W);
- X is one of boron (B), beryllium (Be) and silicon (Si);
- M is at least one of titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), zirconium (Zr), niobium (Nb), molybdenum (Mo), ruthenium (Ru), hafnium (Hf), tantalum (Ta), rhenium (Re), osmium (Os), iridium (Ir), lithium (Li), scandium (Sc), yttrium (Y) or aluminum (Al);
- x is from 0 to 0.999;
- y is at least 4.0;
- n is from 0.001 to 0.999;
- and
- (b) a metal or alloy of formula Tq,
- wherein:
- T is an alloy which is a combination of two or more group 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14 transition metal elements in the Periodic Table of Elements;
- q is from 0.001 to 0.999;
- the sum of q and n is 1;
- and
- q and n are weight percentages;
- wherein the method of manufacturing the composite material comprises:
- i) combining (W1-xMxXy)n and Tq to produce a mixture of (W1-xMxXy)n and Tq;
- ii) blending the mixture (W1-xMxXy)n and Tq to produce a blended mixture of (W1-xMxXy)n and Tq;
- ii) loading the blended mixture of (W1-xMxXy)n and Tq into a die;
- iii) inserting the die into a Spark Plasma Sintering furnace;
- iv) applying pulses of electric current through the die to produce the composite material of (W1-xMxXy)n and Tq.
