在Nb-Si系统中，可以产生由脆性Nb 5Si 3金属间化合物基体和韧性Nb颗粒组成的原位复合材料。这两个阶段是热化学稳定高达1500 ℃，并服从广泛的微观结构的变化，包括形态，体积分数，和个别微观成分的大小。本文介绍了这些复合材料的显微组织和相变作为成分和热处理的函数，以及从室温到1400°C的弯曲性能。
In the Nb-Si system, it is possible to produce in-situ composites consisting of a brittle Nb5Si3 intermetallic matrix and ductile Nb particles. The two phases are thermochemically stable up to ∼ 1500∼C and are amenable to wide microstructural variations including morphology, volume fraction, and the size of the individual microconstituents. This paper presents microstructures and phase transformations in these composites as a function of composition and heat treatments and bend properties from room-temperature to 1400°C.
