Modulated structure in the martensite phase of Ni1.8Pt0.2MnGa: a neutron diffraction study [PDF]
Appl. Phys. Lett. 101, 171904 (2012), 2012 7M orthorhombic modulated structure in the martensite phase of Ni1.8Pt0.2MnGa is reported by powder neutron diffraction study, which indicates that it is likely to exhibit magnetic field induced strain. The change in the unit cell volume is less than 0.5% between the austenite and martensite phases, as expected for a volume conserving martensite ...

Martensitic relief observation by atomic force microscopy in yttria stabilized zirconia [PDF]
Journal of the American Ceramic Society, 86(12), 2225-2227 (2003), 2017 The tetragonal to monoclinic (t-m) phase transformation of zirconia has been the object of extensive investigations of the last twenty years, and is now recognised as being of martensitic nature. However, martensitic transformation has only been observed by transmission electron microscopy or indirect methods.

The effect of reversed austenite on mechanical properties of 13Cr4NiMo steel: a CPFEM study
Journal of Materials Research and Technology, 2022 In order to investigate the effect of reversed austenite on the mechanical properties of 13Cr4NiMo steel, a meso scale crystal plasticity finite element model (CPFEM) was established to simulate the deformation induced martensitic transformation (DIMT ...

Crystallographical Analysis on Martensite Transformation and Martensitic Morphology.
ISIJ International, 1997 The strain tensor and displacement vector associated with lattice deformation were introduced to discuss the effect of self-accommodation and plastic accommodation in martensitic transformation and the crystallographic models for {557} f , {225} f and {31015} f martensite were proposed, along with their experimental verification.

Mechanical and tribological behavior of dual-phase ductile iron with different martensite amounts
Journal of Materials Research and Technology, 2023 Ferrite-martensite (F/M) dual-phase ductile iron with different relative amounts of martensite was fabricated via intercritical quenching in the present study. The mechanical properties and tribological behavior were investigated. The strength of ductile

Journal of Microscopy, Volume 289, Issue 2, Page 73-79, February 2023., 2023 Abstract A modification to picric acid solutions has been undertaken to reveal the prior‐austenite grain boundaries in microalloyed steels as a result of elemental segregation. It has been found the maximum addition of sodium dodecyl sulphate plus hydrochloric acid to fully reveal both the prior austenite grain boundaries and the final post‐processed ...

The "quenching and partitioning" process: background and recent progress
Materials Research, 2005 A new process concept, "quenching and partitioning" (Q&P) has been proposed recently for creating steel microstructures with retained austenite. The process involves quenching austenite below the martensite-start temperature, followed by a partitioning ...

Non-Modulated Martensite Microstructure With Internal Nanotwins In Ni-Mn-Ga Alloys
Archives of Metallurgy and Materials, 2015 The self-accommodated non-modulated martensite of Ni-Mn-Ga single crystal was studied by transmission and scanning electron microscopy in the latter case using the electron backscatter diffraction technique.
