“…Except for common mechanical testing method variety of structural and chemical analyses are employed for characterisation of these new materials. [1,2] To understand the impact of diverse alloying elements and heat treatment upon the (micro) structural characteristics of such novel steels, Mössbauer spectrometry is employed as one of principal method of investigation. In the past, Mössbauer effect technique was shown to provide useful information related to thermal stability of metastable austenite in ledeburitic Cr-Mo-V tool steel.…”

“…In the past, Mössbauer effect technique was shown to provide useful information related to thermal stability of metastable austenite in ledeburitic Cr-Mo-V tool steel. [2,3] They were prepared by rapid solidification of powder particles produced by nitrogen gas atomization. Morphological variations of the solidified microstructure were also examined using Mössbauer spectroscopy.…”

Structural features of novel corrosion-resistant LC 200N steel were investigated. Mössbauer spectrometry was chosen as a principal method of investigation. Surface as well as bulk properties were studied using Conversion Electron Mössbauer Spectrometry and transmission technique, respectively. Complex behaviour of magnetic and non-magnetic phases was identified in the samples by these two techniques. Chemical composition was checked by neutron activation analysis and X-ray fluorescence technique. Structural arrangement was studied by scanning electron microscopy with energy dispersive spectrometry and transmission electron microscopy. They unveiled regions with fairly varied Cr concentrations. Basing on a simple model of two different Cr concentrations, the relative areas of the Mössbauer sextets were modelled by a linear combination of two binomial distributions.

“…Mössbauer spectroscopy enables confirmation of research results [1][2][3][4][5] obtained from the dilatometric, magnetic, X-ray, and microscopic analyses of steels as well as it gives additional data [6][7][8][9][10][11][12]. Significant research difficulties may occur in the case of the analysis of matrix composed of strongly deformed martensite.…”

The Mössbauer spectroscopy studies of matrix changes during continuous heating from as-quenched state of high carbon tool steel

2009

This work presents the results of investigations carried out using Mössbauer spectroscopy technique, and their interpretation concerning ferrite or martensite matrix and its changes during tempering. The changes in the matrix are brought about by the stress relaxation, retained austenite transformation, nucleation and solubility of ε carbides as well as cementite nucleation and growth. This research was conducted on a new high-carbon alloy 120MnCrMoV8-6-4-2 steel, which was designed by the Phase Transformations Research Group, AGH UST, in 1998. Mössbauer spectroscopy was applied not only for magnetic hyperfine field studies, but also for analysis of the values of quadrupole splitting and isomeric shift, what resulted in significant conclusions concerning the changes in matrix chemical composition, microstructure, and the level of stresses being present in it.

“…Many works [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] showed that Mössbauer spectroscopy gives a possibility to obtain new data, which may help more detailed interpretation of the phenomena connected with phase transformations during tempering. This paper presents the results of investigations using Mössbauer spectroscopy and their interpretation concerning retained austenite transformation during isothermal heating from as-quenched state in relation to previously conducted dilatometric and microscopic investigations [1,2].…”

This work presents the results of investigations using Mössbauer spectroscopy technique and their interpretation concerning retained austenite (RA) and its transformation during tempering in relation to previously conducted dilatometric, microscopic and mechanical investigations. This research was conducted on a new high-carbon alloy steel 120 MnCrMoV8-6-4-2, which was designed in 1998, in Phase Transformations Research Group at the AGH UST. The influence of the tempering time on the mechanical and chemical stability of retained austenite and on the products of its transformation, nucleation and solubility of ε carbides and cementite nucleation and growth, was determined.
