通过研究这些系统的放电等离子烧结体的微观结构，构建了第一个尝试性的 Nb-Si-Al 和 Nb-Si-N 三元相图。然后检查了两个系统中具有不同成分的压坯的微观结构、机械性能和氧化行为。 Nb3Si5Al2 基体压块在 1573 K 时表现出极好的抗氧化性，尽管该压块在 1023 K 时表现出较差的抗氧化性。 (C) 2001 Elsevier Science Ltd. 保留所有权利。
First tentative Nb-Si-Al and Nb-Si-N ternary phase diagrams were constructed by investigating microstructures of spark plasma sintered compacts of these systems. The microstructure, mechanical properties and oxidation behavior of compacts with some different compositions in the two systems were then examined. Nb3Si5Al2 matrix compact showed extremely good oxidation resistance at 1573 K, although the compact showed poor oxidation resistance at 1023 K. (C) 2001 Elsevier Science Ltd. All rights reserved.
