“…Furthermore, the decrease in the H indicates a decrease in the magnetic moment [24] which can be attributed to an increase in the electron transfer to the unfilled 3d bands [25]. In our previous similar study on Mo concentrations in Fe-30%Ni-x%Mo (x = 0.8, 1.8, and 2.6) alloys, a nearly smooth line was obtained for the variation in H and δ [10]. The change in H and δ depending on the Mo and Ti ratios was illustrated graphically in Fig.…”

In this study, the influence of Ti content on the microstructure of the martensite bcc α ), which was formed by thermal effect, was investigated by scanning electron microscope and transmission electron microscope observations, in Fe-30Ni-xTi (x = 0.8, 1.8, 2.6) alloys. The crystallographic orientation relationship between austenite fcc (γ) and thermally induced bcc (α ) martensite was found to be as (111)γ//(011)α (Kurdjumov-Sachs (K-S)), by the electron diffraction analysis. The martensitic transformation temperature (Ms) of α martensite was determined as -41• C, -62• C, and -76• C in the alloys with 0.8%, 1.8%, and 2.6% Ti concentration, respectively. The Mössbauer spectrometer analysis has been revealed by a paramagnetic character for the austenite phase and magnetically order character for α martensite phase. Hyperfine magnetic field, isomer shift and volume fractions of phases were determined by the Mössbauer spectroscopy.

“…to Fe-Ni alloys significantly influences their several physical properties, such as martensitic transformation and magnetic properties. Adding a small amount of Si, Mo and Co in Fe-Ni-based alloys have changed martensite phases morphology, the amount of martensite phases rate, and magnetic properties [9][10][11].…”

“…The elements constituting the alloy is one of the important factors affecting the characteristics of martensitic transformation such as hardness of austenite, morphology of martensite, effect of shape memory and magnetic properties of alloys Hyperfine Interact (2016) 237:11 [4][5][6][7]. For instance, even a small amount of Si, Mo or Co addition changes the martensite morphology, magnetic properties and hardness of the alloy [4,6,8,9]. Additionally, increasing Si content causes the martensite morphology to change from lath to twinning martensite plate and the volume fraction of martensite decreases according to a previous study of Gungunes et al [4].…”

Morphological and magnetic properties in Fe-25%Ni-5%Si-x%Co (x = 0, 10, 15) alloys are investigated. Scanning electron microscopy (SEM), Mössbauer spectroscopy and AC magnetic susceptibility measurements are used to determine the physical properties of alloys. The martensite morphology changed depending on the Co content. The Mössbauer study shows that the volume fraction and hyperfine field of martensite increases while isomer shift values decrease with increasing Co content. On the other hand; AC susceptibility results showed that; Co is an effective element which can be used to control both the magnetic transition and martensitic transformation temperatures.

“…Nishiyama describes stabilization of austenite as such a transformation that occurs difficult from austenite to martensite and also classified the stabilization of austenite in three subclasses as chemical, thermal, and mechanical stabilization [4]. As well, there are considerable studies on austenite stabilization and martensite morphologies of Fe-based alloys [6][7][8][9][10][11][12][13]. Gungunes et al [6] examined the influence of thermal stabilization in an Fe-24.5%Ni-4.5%Si alloy.…”

The effect of Si on the austenite stabilization, martensite morphology, and magnetic properties in Fe-26%Ni-x%Si (x=3.5, 5, and 6) alloys have been studied by means of transmission electron microscopy (TEM) and Mössbauer spectroscopy techniques. TEM observations reveal that the martensite morphology is closely dependent on the Si content. The volume fraction changes of martensite and austenite phases, the hyperfine magnetic field, and isomer shift values have been determined by Mössbauer spectroscopy. The Mössbauer study reveals that the hyperfine magnetic field, the isomer shift values and the volume fraction of martensite decrease with increasing Si content.
