Numerical Studies on the Magnetism of Fe-ni-mn Alloys in the Invar Region *
By means of self-consistent semi-empirical LCAO calculations we study the itinerant magnetism of (Fe 0.65 Ni 0.35) 1−y Mn y alloys for y between 0 and 0.22 at T = 0 K, neglecting only the transverse spin components. We find that the magnetic behaviour is quite complicated on a local scale. In addition to ferromagnetic behaviour, also metastable spin-glass-like configurations are found. In the s...
متن کاملHigh Hardness Nanocrystalline Invar Alloys Prepared from Fe-Ni Nanoparticles
High-density (>98% of full density) nanocrystalline invar alloys with significantly enhanced hardness (>240 in Vicker’s hardness) were prepared by sintering compacted Fe-Ni nanoparticles in hydrogen. The precursor Fe-Ni nanoparticles were synthesized by hydrogen plasma evaporation of bulk Fe61Ni39 alloys. The size and the productivity of the Fe-Ni nanoparticles increased with increasing hydroge...

متن کاملNanostructurization of Fe-Ni Alloy
Data about an effect of cyclic γ-α-γ martensitic transformations on the structure state of reverted austenite Fe-31.7 wt.% Ni-0.06 wt.% C alloy are presented. The effect of multiple direct γ-α and reverse α-γ martensitic transformations on fragmentation of austenitic grains has been investigated by electron microscopy and X-ray diffraction methods. An ultrafine structure has been formed by nano...
متن کاملMicroscopic structure of Fe-Ni and Fe-Ni-S molten alloys of geophysical interest
The static S(Q) liquid structure factors for binary FexNi12x , x50.90, 0.85, and ternary Fe0.85Ni0.05S0.15 molten alloys are investigated by means of the concurrent use of neutron diffraction and reverse Monte Carlo simulations. The measured G(r) radial distributions reveal atomic orderings varying from that present in the Fe0.90Ni0.10 alloy, reminiscent of the ideal bcc structure of solid Fe, ...
