Claim 13:
14. A method of forming a cutting element, comprising:
providing a diamond-containing material comprising discrete diamond particles over a substrate;
sintering the diamond-containing material in the presence of a liquid phase of a homogenized alloy to inter-bond the discrete diamond particles, the homogenized alloy comprising:
one first element selected from Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, Hf, Ta, Re, Os, Ir, Pt, Au, Hg, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Ac, Th, Pa, and U; and
two second elements selected from Al, Ga, Sn, Be, Bi, Te, Sb, Se, As, Ge, Si, B, and P; and

converting portions of the homogenized alloy within interstitial spaces between the inter-bonded diamond particles into a thermally stable material comprising a quaternary κ-carbide having the general chemical formula:

A3XZ1-n,

where A comprises the one first element;
X comprises the two second elements;
Z comprises C; and
n is greater than or equal to 0 and less than or equal to 0.75.
