T. Murakami et al., Microstructure, mechanical properties and oxidation behavior of Nb-Si-Al and Nb-Si-N powder compacts prepared by spark plasma sintering, INTERMETALL, 9(7), 2001, pp. 621-627
First tentative Nb-Si-Al and Nb-Si-N ternary phase diagrams were constructe
d by investigating microstructures of spark plasma sintered compacts of the
se systems. The microstructure, mechanical properties and oxidation behavio
r of compacts with some different compositions in the two systems were then
examined. Nb3Si5Al2 matrix compact showed extremely good oxidation resista
nce at 1573 K, although the compact showed poor oxidation resistance at 102
