چکیده
Powders with nanometric crystallites of two ternary alloys Fe0.90Cr0.05Si0.05 and Fe0.85Cr0.10Si0.05 were prepared by mechanical alloying (MA) in a planetary high-energy ball mill at various milling times followed annealing vacuum 900 K to induce an oxygen-induced surface segregation Cr Si atoms. The powders characterized X-ray diffraction (XRD), photoelectron spectroscopy (XPS) scanning electron microscopy (SEM). obtained results show that all crystallize the body-centered cubic structure are composed micrometric particles, which polycrystalline consist many crystallites. mean size particles as well decreases progressively time. In order study anti-corrosion properties materials, exposed atmospheric gases 870 K. After each oxidation step, formation iron oxides was investigated using 57Fe transmission Mössbauer (TMS). It found after 10 20 h MA extremely resistant oxidation. This result can be connected fact XPS measurements reveal high concentration atoms on powder particles.

Production of Fe-TiN and Fe-Ti(N,C) composite powders by mechanical alloying
In this research, the production of Fe-TiN and Fe-Ti(N,C) composite powders by mechanical alloying was investigated and evaluated. Ferrotitanium (containing 70%Ti), titanium and graphite were used as the raw materials. Initial mixtures were milled in different time durations under the pure nitrogen atmosphere with the pressure of 5atm. The results showed that when N2 pressure is 5 at...
متن کاملPhase transitions in nanostructured Fe–Cr–Ni alloys prepared by mechanical alloying
Phase transition of Fe–18Cr–8Ni, Fe–15Cr–15Ni and Fe–15Cr–25Ni alloys during mechanical alloying (MA) and after subsequent annealing as studied. For Fe–18Cr–8Ni and Fe–15Cr–15Ni the resulting structure by MA was a nanostructured single-phase BCC solid solution ( ) which iffers from that predicted from equilibrium phase diagram. Furthermore, the equilibrium structure was not achieved after heat ...

Although Cu and Fe are immiscible under equilibrium conditions, they can form supersaturated solid solutions by mechanical alloying. In this paper, nano-structured of the metastable Cu-Fe phase containing 10, 15, 20 and 25% wt Fe were synthesized by intensive ball milling for 15h, in order to achieve a solid solution of Fe in Cu. The phase composition, dissolution of the Fe atoms into the Cu ma...
متن کاملSimilarities and Differences in Mechanical Alloying Processes of V-Si-B and Mo-Si-B Powders
V-Si-B and Mo-Si-B alloys are currently the focus of materials research due to their excellent high temperature capabilities. To optimize the mechanical alloying (MA) process for these materials, we compare microstructures, morphology and particles size as well as hardness evolution during the milling process for the model alloys V-9Si-13B and Mo-9Si-8B. A variation of the rotational speed of t...

In this work, Al-20Si-10Fe-6Cr and Al-20Si-10Fe-6Mn (wt %) alloys were prepared by a combination of short-term mechanical alloying and spark plasma sintering. The microstructure was composed of homogeneously dispersed intermetallic particles forming composite-like structures. X-ray diffraction analysis and TEM + EDS analysis determined that the α-Al along with α-Al15(Fe,Cr)₃Si₂ or α-Al15(Fe,Mn)...
