Synergism between coherent precipitation strengthening and FCC-HCP type transformation-induced plasticity

Materials & Design, 2022
It is becoming a trend that many strengthening methods are applied at the same time to overcome the strength-ductility trade-off. However, the combination of precipitation strengthening and transformation-induced plasticity (TRIP) is rarely used ...

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

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.

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 ...

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.
