Ternary Al70Cu20Fe10 alloy nano-composites prepared by mechanical alloying are characterized by X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS). The results indicate that after milled for 10 hours, the coordination environment around Cu atoms is changed largely and becomes disordered, but the local structure of Fe atoms still remains as that of α-Fe. This indicates the formin...

In this work, the Cu clustering in Fe under irradiation is investigated using experiments, cluster dynamics and atomistic kinetic Monte Carlo (AKMC) simulations. cast iron model FeCu alloy samples were irradiated with 2 MeV electrons for 143 h at 140 °C. The post-irradiation microstructure was characterized atom probe tomography. Cluster AKMC methods used to simulate same conditions. Both simul...

Introduction: The abundance of Cu in the Earth’s mantle normalized to C1 and Mg is similar to the abundances of Ni and Co [1, 2]. This is surprising as Cu is much less siderophile [2] than Ni and Co. Although a lower bulk Earth abundance of Cu is expected because of its lower condensation temperature, this is not sufficient to compensate for the much lower one bar siderophility of Cu when compa...

The ground states of the mixed 3d-metal dimers TiV, TiCr, TiMn, TiFe, TiCo, TiNi, TiCu, TiZn, VCr, VMn, VFe, VCo, VNi, VCu, VZn, CrMn, CrFe, CrCo, CrNi, CrCu, CrZn, MnFe, MnCo, MnNi, MnCu, MnZn, FeCo, FeNi, FeCu, FeZn, CoNi, CoCu, CoZn, NiCu, NiZn, and CuZn along with their singly negatively and positively charged ions are assigned based on the results of computations using density functional t...

Various indispensable metabolic processes are reliant on minute amounts of essential trace elements i.e., Fe and Cu and on FeCu association as well to maintain normal health. An excess of both elements can render abnormality in liver function. The aim of this work was to evaluate the acute hepatotoxicity of Fe & Cu by analyzing the biochemical functions of liver. Adult male Wistar rats (200g) w...
