Lattice Dynamics of Martensitic Transformations Examined by Atomistic Simulations

, 1997
We have performaed molecular dynamics simulations of Fe(80)Ni(20) alloys using an inter-atomic potential of the EAM-type which allows the simulation of the martensite-austenite transition.

Effect of Co and Fe on the inverse magnetocaloric properties of Ni-Mn-Sn [PDF]

, 2007
At certain compositions Ni-Mn-$X$ Heusler alloys ($X$: group IIIA-VA elements) undergo martensitic transformations, and many of them exhibit inverse magnetocaloric effects.

Phase Transformations in Binary Colloidal Monolayers

, 2015
Phase transformations can be difficult to characterize at the microscopic level due to the inability to directly observe individual atomic motions. Model colloidal systems, by contrast, permit the direct observation of individual particle dynamics and of

Design of a Cobalt‐Free Maraging Steel with Ultra‐High Strength of 2.3 GPa Through Additive Manufacturing

Advanced Science, EarlyView.
A computationally designed, cobalt‐free maraging steel tailored for additive manufacturing achieves an ultra‐high tensile strength of 2.3 GPa with 5.7% elongation. This exceptional strength‐ductility synergy stems from high‐density core‐shell Ni3Ti/NiAl nanoprecipitates, a crack‐resistant composition, and a fine equiaxed grain structure enabled by ...

Visualizing Strain‐Coupled Cryogenic Phase Transitions and Defect Dynamics in Perovskite Quantum Dots Using In Situ STEM

Advanced Science, EarlyView.
Cryogenic cooling induces an orthorhombic‐to‐monoclinic phase transition in CsPbBr3 quantum dots, accompanied by pronounced strain localization at surfaces and interfaces. Multimodal in situ STEM directly visualize reversible defect healing during moderate cryogenic treatment and irreversible degradation upon prolonged exposure, revealing the intrinsic
