A micromechanics-inspired constitutive model for shape-memory alloys [PDF]
, 2007 This paper presents a three-dimensional constitutive model for shape-memory alloys that generalizes the one-dimensional model presented earlier (Sadjadpour and Bhattacharya 2007 Smart Mater. Struct. 16 S51–62).

Overcoming the Damping–Elasticity Paradox via 3D‐Printed NiTiSn Nanocomposite
Advanced Science, EarlyView.Here a 3D‐printed nanoeutectic alloy is designed to exhibit a record‐breaking combination of exceptional damping capacity (tanδ > 0.10) and elastic strain exceeding 4.5% at a high stress ≈1500 MPa, overcoming the damping‐elasticity paradox in high damping alloys.

Prediction of the mechanical behaviour of TRIP steel [PDF]
, 2011 TRIP steel typically contains four different phases, ferrite, bainite, austenite and martensite. During deformation the metastable retained austenite tends to transform to stable martensite.

Metallic Bond Induces Soft Phonon Mode and Anharmonicity in Heusler Alloy
Advanced Science, EarlyView.The fruitful functional performances of metastable Heusler alloys originate from the martensitic transformation driven by the transverse acoustic soft phonon mode, regulated by anharmonicity. This study reveals that the long‐range interaction rooted in metallic bonding between spin‐down d‐orbitals of Ni─Ni induces phonon softening and significant ...
