dc.description.abstractIn this study, microstructural and crystallographic properties of phase transformations occurring with thermal effect in Fe- XMn-Mo-Si (X = 15.14wt.% ve 18.45wt.%) alloys have been investigated. The effects of (wt.%) Mn rates in the alloy on the characteristics of phase transformations were investigated by using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and X-Ray Diffraction (XRD). SEM and TEM investigations was observed that two different martensite (? and ?' ) structures were formed in austenite grain. In addition, in TEM observations, the interface regions were selected over the bright field image. Crystallographic orientation relationships were obtained by the analyses of electron diffraction patterns from the interface regions. ? ? ?' type transformation was observed for ?' particle formation, and orientation relationship was found as (1-11)? // (011)?' , [101]? // [1-11-]?' and, ? ? ? type transformation was observed for ? martensite plate formation, and the orientation relationship was found as (1-11-)? // (0002-)?, [1- 1-0]? // [2-110]?. It was noticed that this orientation relationships were compatible with the literature (Kurdjumov-Sachs and Shoji-Nishiyama orientation relationship). Precipitation phase (carbide) formation was observed in microstructure analyses. The changes in the magnetic properties of the alloys having different rates of Mn as a consequence of thermal effect phase transformations was investigated by using Mossbauer Spectroscopy. The internal magnetic field, volume fractions (transformation rates), isomer shift values and magnetic characteristics of the main and product phases were revealed by Mossbauer Spectroscopy. In the Mossbauer Spectrum, it was noticed that ?-martensite and ?-austenite structures showed paramagnetic single-peak, and ?' -martensite showed ferromagnetic six-peaks. © 2020. The Author(s).
