In situ observation of strain and phase transformation in plastically deformed 301 austenitic stainless steel [PDF]

, 2016
To inform the design of superior transformation-induced plasticity (TRIP) steels, it is important to understand what happens at the microstructural length scales.

Direct Observation of Martensitic Phase-Transformation Dynamics in Iron by 4D Single-Pulse Electron Microscopy [PDF]

, 2009
The in situ martensitic phase transformation of iron, a complex solid-state transition involving collective atomic displacement and interface movement, is studied in real time by means of four-dimensional (4D) electron microscopy.

Phase-field simulation of lenticular martensite and inheritance of the accommodation dislocations

MATEC Web of Conferences, 2015
A phase-field simulation is performed to study the substructure evolution of lenticular martensite in TRIP steels. The evolution of martensitic phase variants and dislocations is calculated by a coupled phase-field micro-elasticity model. The simulations

Effect of C on the Martensitic Transformation in Fe-C Alloys in the Presence of Pre-Existing Defects: A Molecular Dynamics Study

Crystals, 2019
Molecular dynamics simulations are used to investigate the atomic effects of carbon (C) addition in Fe on the martensitic phase transformation in the presence of pre-existing defects such as stacking faults and twin boundaries.

Dynamic elastic properties and magnetic susceptibility across the austenite-martensite transformation in site-disordered ferromagnetic Ni-Fe-Al alloy [PDF]

, 2007
Besides permitting an accurate determination of the ferromagnetic-to-paramagnetic phase transition temperature and the characteristic temperatures for the beginning and end of the growth of martensite (austenite) phase at the expense of austenite ...

Constitutive modeling of metastable austenitic stainless steel [PDF]

, 2007
A stress-update algorithm is developed for austenitic metastable steels which undergo phase evolution during deformation. The material initially comprises only the soft and ductile austenite phase which due to the phenomenon of mechanically induced ...

Adaptive Phase in Martensitic Transformation

Materials Transactions, JIM, 1992
It is shown that an adaptive transient phase can be formed along the martensitic transformation path to overcome thermodynamic and nucleation barriers caused by the transformation strain. A possible role of the adaptive phase in the thermal nucleation of the martensite is discussed.
