Control of Fe in Al alloys is a severe challenge for the full metal circulation to produce recycled with mechanical and physical performance as high primary alloys. The restriction content mainly due deterioration caused by large-scale Fe-containing intermetallic compounds (FIMCs) In this paper, recent knowledge gained regarding nucleation, formation, technical developments on microstructural c...

Alloys of the As2Se3-NdSe system were synthesized in a wide range concentrations. The was studied by differential thermal (DTA), X-ray diffraction (XRD), microstructural (MSA) analysis, as well measuring microhardness and density. has small single-phase fields based on primary components. In system, area solid solution As2Se3 compound at room temperature is 1.5 mol. %, NdSe 2.0 %. Upon slow coo...

Zirconium alloys are subjected to a fast neutron flux in nuclear reactors, inducing the creation of large number point defects, both vacancy and self-interstitial. These defects then diffuse can be trapped by their different sinks or cluster form larger such as interstitial clusters. In this work, trapping capability small-vacancy clusters (two/three vacancies, V2/V3) α-Zr doped with alloying e...

Oxygen and nitrogen introduced in three Ni-Cr alloy castings were significantly varied according to both different alloys and different melting methods. The arc melting in Ar blow caused significant increases in the amounts of oxygen and nitrogen uptake, which were influenced by alloy composition. The severe gas absorption by the arc melting in Ar blow resulted in the marked occurrence of poros...

Hot rolled Al-6Li-1Cu-1Mg-0.2Mn (at.%) (Al-1.6Li-2.2Cu-0.9Mg-0.4Mn, wt.%) and Al-6Li-1Cu-1Mg-0.03Zr (at.%) (Al-1.6Li-2.3Cu-1Mg-0.1Zr, wt.%) alloys developed for age forming were studied by tensile testing, electron backscatter diffraction (EBSD), three-dimensional atom probe (3DAP), transmission electron microscopy (TEM) and differential scanning calorimetry (DSC). For both alloys, DSC analysis...

Powder neutron diffraction studies were performed on three icosahedral alloys of the aluminum manganese system containing 27, 30. and 34 weight percent manganese. All peaks were found at the angles consistent with the icosahedral indexing with a six-dimensional cubic lattice parameter of approximately 0.65 nm that decreased with increasing Mn content. The relative intensities differ significant...

MGssbauer experiments using the 86.5 keV resonance of 1 5 5 ~ d have been performed on Gdl+,Fe4B4 with and without substitution of 20 % of Gd by Nd or Sm. All these alloys are characterized by a very large quadrupolar interaction. At T = 4.2 K, i.e. below the magnetic temperature order, the Miissbauer spectra are quite different for the three alloys, owing to the different direction of the Gd m...

In this research, electroplated magnetically isotropic and anisotropic soft alloys and screen-printed soft ferrites applicable to micromachined micromagnetic devices are fabricated and characterized using in situ measurement techniques. Appropriate magnetic materials and deposition methods, such as electroplating and screen-printing techniques, are examined and material test structures are fabr...

Temperature dependences of the extraordinary Hall coeficient R, and resistivity p, yield a m p 2 (arising from the side-jump mechanism) for the majority of investigated FeCoNi-based alloys. The deviation from p2 variation in Co-rich alloys is probably due to the temperature dependence of the magnetic anisotropy in these alloys. One of the characteristic features of amorphous ferromagnetic alloy...
