Steel products are coated with Aluminum (Al) and Zinc (Zn) alloys to improve their corrosion properties. Bulk steel in batches; however, sheets by a continuous hot-dip galvanizing process. guided into out of the molten Al-Zn-Si (AZ) bath help stainless-steel rolls, known as guiding, sink rolls. These rolls subjected excessive surface AZ and, hence, replaced frequently. The deterioration immerse...

Experimental evidence is presented to show that significant rotations of brittle phase inclusions of a Fe-rich intermetallic phase occur during plastic deformation on an Al Mg Si base wrought aluminum alloy. The particle rotations are quantitatively characterized, for uniaxial tension, compression, torsion, and notch-tension test specimens strained to different strain levels. The particle rotat...

A laboratory-scale submerged anoxic-oxic membrane bioreactor treating municipal wastewater was operated to investigate the structure and distribution of the inorganic cake layer buildup on the membrane. BCR (European Community Bureau of Reference) sequential extraction, X-ray photoelectron spectroscopy (XPS), and both map and line scan of energy-dispersive X-ray analysis (EDX) were performed fo...

Tetragonal magnetostriction (λγ,2) and elastic constants (c′, c44, and c11) for Fe100−xSixwere measured as a function of temperature (T). Compositions corresponding to the disordered A2 (x = 5), ordered D03 (x = 19.8), and mixed (x = 11.6) phases, were investigated. The magnetoelastic coupling (−b1) was determined for 77 < T < 300 K and compared with those of Fe-Ga, Fe-Ge, and Fe-Al. Both λγ,2(...

The title compound, (sodium magnesium) [magnesium iron(III) silicon] disilicate, (Na0.97Mg0.03)(Mg0.43Fe0.17 Si0.40)Si2O6, is isotypic with ordered P2/n omphacite. Its structure is characterized by single chains of corner-sharing SiO4 tetrahedra, extending along the c axis, which are crosslinked by bands of edge-sharing octahedra (site symmetry 2), statistically occupied by (Mg + Fe + Si). Betw...
