Abstract:
A composition includes tungsten (W); at least one element selected from the group of elements consisting of boron (B), beryllium (Be) and silicon (Si); and at least one element selected from the group of elements consisting 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) and aluminum (Al). The composition satisfies the formula W1-xMxXy wherein X is one of B, Be and Si; M is at least one of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Ru, Hf, Ta, Re, Os, Ir, Li and Al; x is at least 0.001 and less than 0.999; and y is at least 4.0. A tool is made from or coated with this composition.
