Abstract
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 3 K. (C) 2001 Elsevier Science Ltd. All rights reserved.
