Cu is known as one of the harmful tramp elements in recycled Fe. In the present work, the effects of Cu on Fe grain boundary (GB) embrittlement have been investigated by first-principles tensile tests. Because the Fe-Cu bonds are rather isotropic and the effects due to their difference in atomic size are negligibly small, the GB atomic structure prior to straining is little changed by Cu segreg...

Khezr-Abad pluton is cropped out in North-West of Taft. This granitoid seems to be younger than the surrounding metamorphosed rocks, particularly the lower cretaceous limestones and probably is implaced during Oligo-Miocene. The most volumetric abundances of the igneous rocks are: granodiorite, granite, quartzmonzo-diorite, quartz-diorite, and in a lesser amount tonalite, quartz-syenite and ...

Two bimetallic assemblies K[Cu(cyclam)][Fe(CN)6] 4H2O 1 and [Cu(L)][Cu(L )][Fe(CN)6] 6.5H2O 2 (cyclam = 1,4,8,11-tetraazacyclotetradecane; L = N,N -bis(2-pyridylmethylene)-1,3-propanediamine and L = N-2-pyridylmethylene-1,3-propanediamine) have been prepared from the reaction of [Fe(CN)6] 3 and the precursors [Cu(cyclam)] and [Cu(L)] , respectively, and their structure and magnetic properties s...

Iranian Cenozoic magmatic belt, known as Urumieh-Dokhtar, is recognized as an important polymetallic mineralization which hosts porphyry, epithermal, and polymetallic skarn deposits. In this regard, multivariate analyses are generally used to extract significant anomalous geochemical signature of the mineral deposits. In this study, stepwise factor analysis, cluster analysis, and concentration–...

An experiment was conducted to evaluate the effect of dietary content and combinations of Zn, Fe, and Cu on deposition of these elements in egg components, liver, and excreta. Excreta were applied as a manure to a lawn, and 3 mo later soil and herbage samples were taken and analyzed. The experiment comprised 144 hens in 8 groups. The basal diet contained Zn, Fe, and Cu at 63.4, 92.8, and 9.0 mg...

This study was to examine the relationship between uteroferrin and Fe, and Fe and Cu in the fetal pig. In Exp. 1, conceptus tissues and fluids were obtained on d 30, 45, 60, 75 and 90 of gestation for Fe and Cu analyses. In fetus minus liver, total Fe and Cu increased constantly between d 30 and 90, but Fe and Cu concentrations (microgram/g dry tissue) both decreased between d 30 and 45 and the...
