Thermodynamic assessment of the metastable liquidi in the Al–In, Al–Bi and Al–Pb systems

Abstract

The metastable liquidi in the Al-In, Al-Bi, and Al-Pb systems were assessed through the thermodynamic modelling of the liquid miscibility gaps. The subregular solution model was applied to describe the Gibbs free energy of liquid phases and the interaction parameters were optimized using the phase diagram data. In addition, spinodal curves were assessed to predict the possible regions for metastable phases. The present results were compared and discussed with other experimental and assessed data available from the literature.

SHAPE MEMORY EFFECT AND CYCLIC DEFORMATION BEHAVIOR OF Ti–Nb–N ALLOYS

“…[1][2][3] In addition, it has been reported that some Ti-Nb base alloys, such as Ti-(26-27) at.%Nb, 4,5 Ti-Nb-Sn, 6 Ti-Nb-Zr, 7 Ti-Nb-Ta, 8 exhibited superelasticity at room temperature. The superelastic recovery strains of these alloys are small compared with Ti-Ni superelastic alloys mainly due to the low critical stress for slip and small transformation strain.…”
