Structure and Giant Inverse Magnetocaloric Effect of Epitaxial Ni-Co-Mn-Al Films

, 2015
The structural, magnetic, and magnetocaloric properties of epitaxial Ni-Co-Mn-Al thin films with different compositions have been studied. The films were deposited on MgO(001) substrates by co-sputtering on heated substrates. All films show a martensitic

The evolution of microstructure, martensitic transformation and mechanical properties in Ti–V–Al-based shape memory alloys with changing annealing temperatures

Journal of Materials Research and Technology, 2022
In the present study, the effects of annealing temperature on the microstructure, martensitic transformation and mechanical properties of Ti–V–Al-Gd shape memory alloys were investigated. The results revealed that the phase constituents were dependent on

Crystallography and ageing effect associated with thermoelastic martensitic transformations [PDF]

, 1996
Martensitic transformation means the first-order diffusionless phase transformation in solids. Originally, a particular microstructure observed in quenched steels was called "martensite", in recognition of the well-known German metallurgist A.

Dynamic Martensitic Phase Transformation in Single-Crystal Silver Microcubes [PDF]

SSRN Electronic Journal, 2019
Abstract The ability to transform the crystal structure of metals in the solid state enables tailoring their physical, mechanical, electrical, thermal, and optical properties in unprecedented ways. We demonstrate a martensitic phase transformation from a face-centered-cubic (fcc) structure to a hexagonal-close-packed (hcp) structure that occurs in ...

Phase diagram of FeNiCoAlTaB ferrous shape memory alloy on aging time

AIP Advances, 2017
Ferrous shape memory alloy, Fe41Ni28Co17Al11.5Ta2.5B0.05, has shown large superelastic strain and strength in previous study. In the fabrication of this alloy, aging process is crucial for the formation of shape memory effect/superelasticity.

Premartensitic Transition in Ni2+xMn1-xGa Heusler Alloys

, 2001
The temperature dependencies of the resistivity and magnetization of a series of Ni2+XMn1-XGa (X = 0 - 0.09) alloys were investigated. Along with the anomalies associated with ferromagnetic and martensitic transitions, well-defined anomalies were ...

Influence of intermartensitic transitions on transport properties of Ni2.16Mn0.84Ga alloy

, 2004
Magnetic, transport, and x-ray diffraction measurements of ferromagnetic shape memory alloy Ni$_{2.16}$Mn$_{0.84}$Ga revealed that this alloy undergoes an intermartensitic transition upon cooling, whereas no such a transition is observed upon subsequent ...
