Martensite transformation induced superplasticity and strengthening in single crystalline CoNiCrFeMn high entropy alloy nanowires: A molecular dynamics study

, 2020
In this work, we report simultaneous superplasticity and strengthening in single crystalline face-centered cubic (FCC) CoNiCrFeMn high entropy alloy (HEA) nanowires through synergistic martensitic phase transformation and micro-twin nucleation as ...

Effect of Cu on Martensite Transformation of CoCrMo alloy for biomedical application

, 2020
The martensite transformation of Co-29Cr-6Mo-xCu (Co-xCu, x = 0 , 1.5 , 2 , 4 , wt%) alloys was investigated in order to explore ductile Co-based alloy without Ni for biomedical application.

Influence of Ni/Ti ratio and Nb addition on martensite transformation behavior of NiTiNb alloys

Journal of Alloys and Compounds, 2019
Based on the designed NixTiyNbz (x/y = 1, 1.0210, 1.0425, 1.0645, 1.0869/x-y≈0, 1, 2, 3, 4; z = 0, 2, 4, 6, 9) alloys, influence of Ni/Ti ratio and Nb addition on martensite transformation behavior of NiTiNb alloys is elaborately examined.

Mechanically-induced martensite transformation of NiTiFe shape memory alloy subjected to plane strain compression

, 2020
Based on the channel die compression, NiTiFe shape memory alloy (SMA) was subjected to plane strain compression. Mechanically-induced martensite transformation, nanocrystalline and amorphous phase can be observed in the case of large plastic strain ...

Role of stacking faults in martensite transformation of FeMnSiCrNi shape memory alloy subjected to plastic deformation at high temperatures

, 2020
FeMnSiCrNi shape memory alloy (SMA) undergoes plastic deformation at high temperatures, including 850, 900, 950 and 1000 °C. All the deformed FeMnSiCrNi samples consist of γ austenite and e martensite, where the orientation relationship between γ ...

Continuous strengthening in nanotwinned high-entropy alloys enabled by martensite transformation

, 2020
Strengthening by nanotwins in metals has been widely reported to have a limit, i.e., softening occurs when the twin thickness is reduced below a critical value, similar to the Hall-Petch breakdown in nanocrystalline materials.

Martensitic transformation of Ca

Physical Review B, 1990
A la temperature ambiante, Ca subit une transformation structurale induite par la pression de 20 GaPa, passant de la structure cubique a faces centrees a cubique centre. On examine un modele de distorsion pour cette transformation. Le mecanisme de Bain est un cas particulier de la distorsion triclinique plus generale, et des lors qu'un chemin dans cet ...

Isothermal martensitic transformations

Uspekhi Fizicheskih Nauk, 2005
Martensitic transformations have long been considered most characteristically athermal — in the sense that they develop, with changing temperature, at a tremendous temperature-independent rate and cease to occur at isothermal conditions. Over the past decades, however, isothermal martensitic transformations (IMTs), which develop at low temperatures for

Simulated Martensitic Transformations

MRS Proceedings, 1983
ABSTRACTMolecular dynamic computer simulations have recently provided some very graphic portrayals of how model lattices can surmount nucleation barriers of various types and accomplish certain kinds of first order displacive transitions. A survey of the different two-and three-dimensional transformations observed to date, along with relevant details ...

Effect of Si doping on microstructure and martensite transformation in Ni-Mn-Sb ferromagnetic shape memory alloys

Intermetallics (Barking), 2018
We have recently reported that the quaternary Ni49.0Mn38.4Sb11.7Si0.9 alloy showed enhanced refrigeration capacity due to the wide working temperature interval and narrow magnetic hysteresis loss via Si-doping.
