Superconductivity and magnetic properties of Nb—Al phases: Nb2Al and NbAl3

Preparation of Niobium Aluminium Alloy Based on Shock Compression Method

“…Nb-Al alloys recently attracted wide attention as high-temperature structural materials due to their low density, high melting point, high toughness and excellent high temperature strength [11,12]. It is well known that the Nb-Al binary system consists of Nb 3 Al, Nb 2 Al and NbAl 3 intermetallics [13,14]. Among them, there is no literature to show the preparation of Nb-Al alloys under shock waves produced by light-gas guns.…”

Electronic and Mechanical Properties of Tetragonal Nb2Al Under High Pressure: First-Principles Calculations

“…Within the best of our knowledge, Nb 2 Al has been extensively studied experimentally [9][10][11][12]. Rios et al [10] used a Bridgman type facility to directionally solidify Al-Nb eutectic alloy.…”

“…They found that Nb 2 Al grown preferably along the (210) and (420) directions. Leyarovski et al [11] investigated the superconductivity and magnetic properties of Nb-Al phases. They showed that the superconducting transition temperature and magnetic susceptibility of Nb 2 Al were 0.74°K and (1.0 ± 0.1) × 10 −6 emu/g, respectively.…”

Stable Properties of NbAl3 under High Pressure: Theoretical Predictions and First-Principles Calculations

“…Based on the Gibbs energy of formation, George et al [6] found that NbAl 3 was the most stable compound in the Nb-Al system. To the best of our knowledge, many investigations have been carried out on NbAl 3 [7][8][9][10][11][12]. Xu et al [10] found that the stability of NbAl 3 compound was depended on the covalent interactions between Al-p and transition-metal Nb-d states.…”
