ABSTRACTNb-Al-N and Nb-Si-B powder compacts were prepared by spark plasma sintering, and their microstructure, mechanical properties and oxidation behavior were investigated. Adding nitrogen was easily done by blending or mechanically alloying Nb and AIN powders and then sintering them. The addition of nitrogen caused the formation of Nb2N in all the Nb-Al-N compacts and Nb2N and Nb3Al2N in compacts with high aluminum and nitrogen contents. The highest room-temperature hardness and the highest yield stress at 1473K were observed for compacts consisting of Nb2N and Nb3Al2N and those consisting of Nb2N and Nb2Al, respectively. Nb-Si-B compacts were prepared from elemental powders. Two or three of NbB2, Nb5Si3, Nb5Si3B2 and NbSi2 phases were identified as constituent phases of Nb-Si-B compacts depending on composition unless a large amount of silicon is consumed by forming SiO2. Contributions of NbB2, NbSi3 and Nb5Si3B2 phases to room-temperaturehardness and yield stress at 1973K were much larger than those of NbSi2. However, the oxidation resistance of Nb-Si-B compacts increased with increasing the volume fraction of NbSi2.The oxidation resistance of NbSi3B2 was better than that of NbSi3, but was not as good as that of NbSi2.

Amorphous Al–Cu–Ti metal foams were prepared by spark plasma sintering (SPS) process with the diameter of 10[Formula: see text]mm. The SPS process was conducted at the pressure of 200 and 300[Formula: see text]MPa with the temperature of 653–723[Formula: see text]K, respectively. NaCl was used as the space-holder, forming almost separated pores with the porosity of 65 vol%. The microstructure and mechanical behavior of the amorphous Al–Cu–Ti metal foams were systematically investigated. The results show that the crystallinity increased at elevated temperatures. The effect of pressure and holding time on the crystallization was almost negligible. The intermetallic compounds, i.e. Al–Ti, Al–Cu and Al–Cu–Ti were identified from X-ray diffraction (XRD) patterns. It was found that weak adhesion and brittle intermetallic compounds reduced the mechanical properties, while lower volume fraction and smaller size of NaCl powders improved the mechanical properties.
