Fabrication of Nb-Based Alloy via Spark Plasma Sintering

Abstract:

Nb-5 at.% W-5 at.% Mo-2 at.%Zr-2 at.% C (Nb5522) bulk alloys were prepared using blended powders or ball-milled powders via spark plasma sintering. The differences between blended powder compacts and ball milled powder compacts with respect to their density, microstructure and mechanical properties were studied. The results showed that ball milling enhances the sinterability of Nb5522 powders. After sintered by SPS at 1873 K, the milled powders achieved a near-full densification density. The SPS process favors the precipitation of (Nb, Zr)C particles.
