Phase equilibria in the Al-Nb-V system are important data for the design of innovative Al-containing refractory-high-entropy alloys, however issues still open in this system. In the present work, Al-Nb-V phase equilibria at 1200 °C were re-investiga

In the present work, the Ta-B system was thermodynamically optimized based on the CALPHAD method using data of liquidus temperatures, invariant transformations and enthalpy of formation from the literature as well as new experiments performed in our

In this work a re-investigation of the solubility limits of the (Nb), Nb3Al, Nb2Al and the Nb-rich side of the NbAl3 phases on the Nb-Al system is presented. Alloys in the binary fields ((Nb)+Nb3Al, Nb3Al+Nb2Al and Nb2Al+NbAl3) were arc-melted, and t

Me-Si-B (Me—metal) alloy systems have been evaluated to aid the development of ultra high temperature structural materials. In the present work, the phase relations at 1700 °C in the Nb-NbSi2-NbB2 region of the Nb-Si-B system have been experimenta
