Shear-induced α → γ transformation in nanoscale Fe-C composite [PDF]

, 2006
High-resolution transmission electron microscopy and three-dimensional atom probe observations show clearly that a reverse transformation of body-centred cubic ferrite to face-centred cubic austenite occurs during severe plastic deformation of a ...

STRESS INDUCED MARTENSITIC TRANSFORMATION IN Ti-20V

Le Journal de Physique Colloques, 1982
The deformation induced product in Ti-2C%V is characterized and the influence of this "transformation" on the deformation behaviour of this alloy is studied. Flate shaped stress assisted products are shown to consist of the orthorhombic α'' phase and the ω phase in the matrix of a β-orientation which is twin related to the parent grain.

Effects of Vacuum-Carburizing Conditions on Surface-Hardened Layer Properties of Transformation-Induced Plasticity-Aided Martensitic Steel

Metals, 2017
The effects of carbon potential in vacuum-carburization on the surface-hardened layer properties of the 0.2%C-1.5%Si-1.5%Mn-1.0%Cr-0.05%Nb transformation-induced plasticity-aided martensitic steel were investigated for the fabrication of precision gears.

Comparison of Stress-induced Martensitic Transformation Under Tension and Compression in Fe-28Mn-6Si-Cr Shape Memory Alloy

EPJ Web of Conferences, 2018
In the case of the NiTi alloy, some research works reported that the stress-strain curve differs significantly between tension and compression. It is considered that the difference in stress-induced martensitic transformation behavior may be observed ...

Dynamic mechanical performance of FeNiCoAl-based high-entropy alloy: Enhancement via microbands and martensitic transformation

Materials Today Advances, 2023
The non-equiatomic FeNiCoAlTaB high-entropy alloy exhibits outstanding quasi-static mechanical properties. Here, we investigate the microstructural evolution and mechanical response of this alloy subjected to dynamic loading, which has not been done ...
