We calculate the electronic properties of austenite and martensite Fe-9%Mn alloys using the self consistent full-potential linearized-plane-wave method under the generalized gradient approximation full lattice relaxation. By minimizing total-energy, the lattice constants in their ground states were determined. We discuss the total energy dependence of the volume, and density of states (DOS).

X-ray photoelectron spectroscopy (XPS), electron microprobe microanalysis (EPMA), and secondary ion mass spectrometry (SIMS) have been used for analyzing the chemical composition in surface layers of iron-base alloys. Samples analyzed in this study were a ferritic Fe–Mn alloy annealed under low partial pressure of oxygen and an austenitic Fe–Mn–Si–Cr alloy annealed under vacuum. The XPS results showed that manganese was enriched and oxidized while iron was metallic in the surface layer of the Fe–Mn alloy annealed under a low partial pressure of oxygen. The EPMA results showed that manganese was depleted while chromium was enriched in the surface layer of the Fe–Mn–Si–Cr alloy annealed under vacuum. The SIMS depth profiles coupled with the EPMA results indicated that the enrichment of chromium in the surface layer improves the oxidation resistance of the alloy. The enrichment and depletion of manganese in the surface layer is discussed on the basis of the thermodynamic properties of the iron–manganese system.

steelmaking slag. The first step is to sulfurize the slag, pro- ducing a liquid sulfide phase (matte) without P. High-purity Fe-Mn alloys can then be made by desulfurizing the matte. However, to our knowledge, there have been no reports to date concerning the sulfurization of P and Mn contained in molten slag. Therefore, knowledge of the distribution of Fe, Mn and P between the matte and the molten slag is re- quired to determine the feasibility of this process. In this study, the equilibrium distributions of Mn, Fe, Ca and P be- tween a FeS-MnS matte and FeO-MnO-SiO2-MgO

, shape memory al- loys, and a rather inexpensive damping material [1 – 4]. In considering the engineering materials, the main problem with Fe-Mn alloys is that they have a poor wear-resistance and microhardness [1, 5, 6]. Coating with certain compounds is one way of improving the hardness, wear resistance, fracture and yield strength of such material [7, 8]. One of the coating techniques is boronizing, a thermo-chemical surface treatment in which boron atoms diffuse into the surface of the work piece to form hard borides with the base material. It is a prominent choice
