Claim 2:
3. 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 comprising at least 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 at least one second element selected from Al, Ga, Sn, Be, Bi, Te, Sb, Se, As, Ge, Si, B, and P to inter-bond the discrete diamond particles; and
converting portions of the homogenized alloy within interstitial spaces between the inter-bonded diamond particles into a thermally stable material substantially free of Co, the thermally stable material comprising one or more carbide precipitates having the general chemical formula:

A3XZ1-n,

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