1. A method of manufacturing a composite material, wherein the composite material comprises:
(a) a first composition comprising a first 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 0.5 to 0.999; and
(b) a second composition comprising a second formula Tq,
T comprises an alloy which is a combination of four 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 0.5;
the sum of q and n is 1; and
q and n are weight percentages;
wherein the composite material has an average Vicker's hardness of about 10 to about 30 GPa as measured under a force of 9.8 N (1 kgf), and
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;
iii) loading the blended mixture of (W1-xMxXy)n and Tq into a die;
iv) inserting the die into a Spark Plasma Sintering furnace; and
v) applying pulses of electric current through the die to produce the composite material of (W1-xMxXy)n and Tq.
