“…These phases are similar to those observed by Y. K. Lee et al 10 , J. Martinez et al 11 and H. Hermawan et al 13 in various Fe-Mn binary alloys at room temperature. Figure 4 shows observed peaks for the FeMn17 alloy and two starting materials, pure Fe and Mn.…”

“…Three phases were identified: austenitic γ, martensitic ε and α′, with γ being the main phase. As per the Fe-Mn binary phase diagram [14], at room temperature (RT) only γ-phase exists for the Fe35Mn composition [14]. It has been reported that in Fe-Mn alloys with less than 10%Mn, only the martensitic α′ phase (BCC) is obtained at RT and in alloys with Mn content between 10 and 15 wt% another martensitic ε phase also occurs at RT [14].…”

The presence of martensites ε and α′ in Fe-35%Mn alloy in our study may be attributed to some local compositional inhomogeneity in the sintered sample.…”

Biodegradable stenting and implantation materials have received considerable attention in biomaterials community, with magnesium having been received most wide attention. However, magnesium corrodes too fast by nature, in human body environment. A new type of biodegradable metal -Fe and its alloys -has been introduced in recent years. In this study, a Fe35wt%Mn alloy was produced using powder sintering. Powder mixture was mechanically milled, pressed and then sintered to consolidate powder compacts. Microstructure characterization and hardness measurement were carried out on the as-sintered samples. In vitro degradability evaluation of the samples was performed in 5% NaCl and Simulated Body Fluid (SBF) media. The experimental results show that a higher porosity results in a higher degradation rate. All samples, with porosity being from 6.5% to 12.2 %, revealed a degradation rate from 0.6 to 1.4 mm/year.

“…In order to correctly evaluate the experimental DH m , the fraction of " phase f " induced by the MT after quenching must be determined independently, since it varies with the content of Mn [3]. Recently, new measurements of DH m have been obtained [4] by combining differential scanning calorimetry (DSC) with MS and dilatometry measurements. In that work [4], MS yielded a "-phase fraction about 30% larger than that of dilatometry.…”

The results of a Mössbauer spectroscopy (MS) and a neutron diffraction (ND) study carried out on a set of Fe-Mn alloys quenched from high temperatures are reported. Upon quenching the high temperature stable phase FCC () together with metastably retained HCP-(") phase are formed. The lattice parameters obtained using ND are in excellent agreement with previous results of the literature. The phase fractions obtained from MS are coincident, within experimental errors, with those extracted from ND, with exception of the case of an alloy with the lowest Mn content (16.8 at.% Mn). That situation can be associated with the occurrence of a high density of stacking faults (SF) in the phase or to the presence of a paramagnetic phase. " phase fractions obtained from MS and ND decrease smoothly with Mn content but are always larger than the values reported in literature resulting from dilatometry.
