The selective laser melting (SLM) of o-Cr-Mo-W/316L composite with 10 wt% Co-Cr-Mo-W addition to 316L stainless steel (SS) powder is produced explore it’s the corrosion behavior. tensile experiment SLM composites also measured investigate difference between two samples. optimum parameters SS and samples are obtained by adjusting power scanning speed relative density 99.04 ± 0.69 99.15 0.43. yie...

It is considered that cow's milk is almost complete food for human as it provides most of the micronutrients and macronutrients. The cow's milks are essential for the growth and development especially for children. The main compositions of cow's milk are protein, fat, carbohydrates, vitamins and minerals which are well defined. Presently, the study of micronutrients and toxic elements in cow's ...

In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on chemical composition of steels. In addition, ...

Iron-based soft magnetic composites (SMCs) are the key components of high-frequency electromagnetic systems. Selecting a suitable insulating oxide layer and ensuring integrity homogeneity heterogeneous core–shell structure SMCs essential for optimizing their properties. In this study, four types SMCs—Fe-Si-Cr/ZrO2, Fe-Si-Cr/TiO2, Fe-Si-Cr/MgO, Fe-Si-Cr/CaO—were prepared via ball milling, follow...

Nanostructured TiN/TiB2/Fe–Cr–Ni composite powder has been prepared via high energy ball milling. Ti and BN powders are reacted to form uniform mixture of TiN and TiB2 within 2 h of milling by a mechanically activated self-sustaining reaction (MSR). The crystallite sizes of TiN nd TiB2 are about 7 and 16 nm, respectively, after 32 h of milling. Through liquid phase sintering and optimizing the ...

The diruthenium compound [Ru(2)(O(2)CMe)(4)](3)[Cr(CN)(6)] contains two weakly coupled, ferrimagnetically ordered sublattices occupying the same volume. Due to the weak, antiferromagnetic dipolar interaction K(c) ≈ 5 × 10(-3) meV between sublattices, a small magnetic field H(c) ∼ K(c)/μ(B) ≈ 800 Oe aligns the sublattice moments. Powder neutron-diffraction measurements on a deuterated sample co...

In this study, the hydrothermal method was used to synthesize MIL-101(Cr), and activated carbon (AC) with different content incorporated in thereby obtaining AC-MIL-101(Cr) composite material a huge specific surface area. The physical properties of MIL-101(Cr) were characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), nitrogen ad...

X-ray absorption fine-structure (XAFS) data were obtained for the V K-edge for a series of anisotropic single crystals of (Cr(x)V(1-x))(2)O(3). The data and the results were compared for the as-prepared bulk single crystals (measured in fluorescence in two different orientations) and those ground to powder (measured in transmission). For the bulk single crystals, the glancing-emergent-angle (GE...

Neutron activation analysis was employed in a survey of weathering abilities of rock surface microorganisms. A yeast isolated from an amphibolite of a megalithic grave was found actively to concentrate, in media and in or on cells, iron and other elements when grown in the presence of ground rock. This was demonstrated by comparing a spectrum of neutron-activated amphibolite powder (particle si...

Coal bed natural gas (CBNG) produced water is usually disposed into nearby constructed disposal ponds. Geochemistry of produced water, particularly trace elements interacting with a semiarid environment, is not clearly understood. The objective of this study was to collect produced water samples at outfalls and corresponding disposal ponds and monitor pH, iron (Fe), aluminum (Al), chromium (Cr)...
