Waste chloride pickle liquors from hot-dip galvanizing plants, steel plants and flue dust contain reasonable amounts of heavy metals such as Zn, Cr, Ni, etc. Iron is invariably associated with most these materials comes into solution during leaching. Thus, the synergistic extraction zinc(II) iron(III) leach solutions in tri-n-butyl phosphate (TBP)–di(2-ethylhexyl) phosphoric acid (D2EHPA) system diluted kerosene was investigated. The Zn Fe concentrations liquor used present study were 2 g/L....
Multi-principal element alloys represent a compelling avenue for the development of innovative that have potential to surpass conventional in various applications, owing extensive compositional space they offer. For structural application though, this has not yet been realized, mostly because hardly superior mechanical properties and elevated alloying costs. To overcome hurdle, efforts made increase using individual strengthening mechanisms, such as grain refinement, prior plastic...
In the present work, Al–Co–Mn ternary system is thermodynamically modelled using Calphad approach. modelling, experimental data such as liquidus, solidus, tie lines, and phase boundaries are included. An order–disorder model used to describe bcc B2 phases. The bcc/B2 description was modified in binary Al–Co improve fit of equilibria system. thermodynamic models Al5Co2, M-Al13Co4, γ1, γ2 intermetallic phases were include third element reflect solubility this T-AlCoMn described a stoichimetric...
Navigating through the phase space of multi-principal element alloys (mpeas) with desired microstructures and outstanding properties is challenging due to extremely high degrees freedom in alloy composition processing conditions. Separate Al C additions resulting precipitation hard phases are commonly used strengthen CoCrFeMnNi-type alloys. However, combined alloying effect especially hardening potential solid solution mpeas rarely investigated, but few existing investigations reveal a...

The development of multi-principal element alloys requires the navigation within a multi-dimensional composition space, which has proven to be challenging. Various methods predict state an alloy, in particular if it is single-phase or not, have been tested with various success. only approach that can consistently constitution e.g. single-phase, multi-phase, intermetallics, thermodynamic calculations using Calphad databases. Conventional databases, such as steel Ni-base, are limited use since...
In this study effect of Stearamide as a corrosion inhibitor for mild steel in hydrochloric acid media was investigated employing various electrochemical techniques include potentiodynamic polarization, impedance spectroscopy (EIS) and liner polarization resistance (LPR). view the fact that is an insoluble compound water, its inhibitive examined by dissolving 10000ppm it into organic solvent followed immersing surface solution 7, 15, 30 60 minutes. As result immersion solution, allowed to be...
Abstract Five thiosalicylic acid (TSA) complexes were prepared. The 1H NMR of these recorded and analysed. It was found that molybdenum, arsenic, selenium, silver tellurium metals coordinates through the sulfur atom. chemical shift ring protons As, Se Te to low field upon complexation, while it shifts high when TSA complex with Ag Mo
