A multifunctional NiTi alloy with Invar (dimension-invariant), Elinvar (elastic modulus-
invariant) and Rinvar (resistivity-invariant) properties over the temperature range from 125 K …

An active learning approach to train machine-learning interatomic potentials (moment tensor
potentials) for multicomponent alloys to ab initio data is presented. Employing this approach …

Shape memory alloy (SMA) sheets processed via unidirectional rolling (UniR) exhibit
macroscopic low thermal expansion (TE) over a wide temperature span but only along a …

Temperature-independent elastic modulus is termed as Elinvar effect, which is available by
tuning the continuous spin transition of ferromagnetic alloys via composition optimization …

Temperature coefficient of elastic modulus can be positive for metastable β phase in titanium
