Magneto-Structural Properties of Ni2MnGa Ferromagnetic Shape Memory Alloy in Magnetic Fields

open access: yesMetals, 2013
The purpose of this review was to investigate the correlation between magnetism and crystallographic structures as it relates to the martensite transformation of Ni2MnGa type alloys, which undergo martensite transformation below the Curie temperature. In

Can Martensitic Phase Transformation Measured by Magnetic Methods be an Indicator of Fatigue Damage in Austenitic Steel at Elevated Temperature and Thermo-Mechanical Loading?

open access: yesResearch and Review Journal of Nondestructive Testing, 2023
The phenomenon of phase transformation from paramagnetic γ austenite to ferromagnetic α' martensite in metastable austenitic stainless steels under fatigue loading is well investigated, especially at ambient temperature.

Martensitic phase transformation in TiNi [PDF]

open access: yesScientific Reports, 2019
AbstractFrom temperature dependent perturbed angular correlation (PAC) measurements (77–873 K) in equiatomic TiNi intermetallic alloy, martensitic phase transformations have been observed. Three frequency components corresponding to three different phases of TiNi have been found in the temperature range 298–873 K.

New insights into the effects of deformation below-MS on isothermal kinetics of bainitic transformation

open access: yesJournal of Materials Research and Technology, 2020
Both ausforming and austempering below the martensite start temperature (MS) have been shown to accelerate the bainitic transformation. This work investigates the combined effects of deformation and austempering below the MS on the isothermal ...

Nanostructured bainite transformation characteristics in medium-carbon steel subjected to ausforming and isothermal holding below martensite start temperature

open access: yesJournal of Materials Research and Technology, 2023
The influence of martensite on the transformation rate of bainite as well as enhancement of various properties is well established, yet the combined influence of both the primary martensite and low temperature ausforming below the martensite start ...

Distributions of avalanches in martensitic transformations [PDF]

open access: yesPhysical Review Letters, 1994
An experimental study of the acoustic emission generated during a martensitic transformation is presented. A statistical analysis of the amplitude and lifetime of a large number of signals has revealed power-law behavior for both magnitudes. The exponents of these distributions have been evaluated and, through independent measurements of the ...

The role of the austenite grain size in the martensitic transformation in low carbon steels

open access: yesMaterials & Design, 2019
There is sufficient experimental evidence to propose that the formation kinetics of athermal martensite directly depends on the austenite grain structure from which the martensite forms. Yet, this dependence is frequently ignored.
