Annealing of dilute binary Cu(Ti), Cu(In), Cu(Al), Cu(Sn), Cu(Mg), Cu(Nb), Cu(B), Cu(Co) and Cu(Ag) alloy films resulted in the strongest <111> fiber texture for Cu(Ti) and the lowest resistivity for Cu(Ag). The behavior of the alloy films was compared and contrasted with that for a pure evaporated Cu film. Electron beam evaporated films with compositions in the range of 2.0-4.2 at% and thickne...

A mercury plating technique was used to determine the phases forming on experimental Ag-Sn-Cu alloy powders (with and without Pd) exposed to electrolytically deposited mercury. Four series of alloy powders were made: a) 1.5% Pd with 10-14% Cu (CU series); b) 1.0% Pd with 10-14% Cu (1PD series); c) 1.5% Pd with different ratios of Ag3Sn (gamma) to Ag4Sn (beta) with 12% Cu (AGSN series); and d) 9...

Structures operating at high temperatures and exposed to aggressive gaseous media are made of low-alloy molybdenum TsM-10 of the system Mo-Al-B, TsM-6 of the system Mo-Zr-B and TsM-12 of the system Mo-Zr-Hf-B [1, 2]. Alloy TsM-10 is commercially pure molybdenum deoxidized by aluminium and boron. Alloy TsM-6 is alloyed with up to 0.2 wt. % zirconium and TsM-12, is alloyed with up to 0.03 wt. % z...

To investigate the irradiation properties of Mo-Re alloy of low Re content (atm%: 0% 8:4%), Mo-Re alloy films were irradiated by 200 keV xenon ions at the dose of 5 10 ions/cm. Different irradiation effects were observed on the samples of different Re content. While the sample of pure Mo remained the same after irradiation, obvious localized amorphization phenomenon took place in the sample wit...

Nanosize-controllable Cu, Ag, Pd, Ni, CuPd alloy and Cu-Ag bimetal encapsulated in inert carbon shells can be synthesized by carbonization of metal-cyclodextrin complexes with a remarkable capability of experimentally determining the size-dependent melting temperature depression of many metal or alloy nanoparticles.

Three hybrid networks based on octamolybdate building units, Cu(I)(8)BBTZ(6)[(α-Mo(8)O(26))(β-Mo(8)O(26))] (1), (Cu(I)BBTZ)(4)[Mo(7)Cu(II)O(24)(H(2)O)(2)]·6H(2)O (2), and Cu(II)Cu(I)(2)BBTZ(5)[β-Mo(8)O(26)] (3) (BBTZ = 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene), have been synthesized under ionothermal conditions and structurally characterized by single-crystal X-ray diffraction. 1 exhibits a rar...

the concentrations and speciation of mo, together with fe, cu, and zn, in nver river sediments impacted with mo mining activities in western liaoning, northeast china, were investigated withgeochemical method. using the x-ray fluorescence and x-ray diffraction, the characterizations of metals in tailings ponds deposited along the nver river bank were analyzed. analysis and comparison of the con...

Gold alloys with Cu contents of 10 mass%, 20%, and 30% were used for morphological observation of porous surface structures after heating at 800 degrees C in air followed by pickling with acid solution. With increasing Cu content in the gold alloy, the internal oxidation zone became well-developed in the alloy matrix. The mechanism by which a porous structure was formed on the surface of a gold...

Due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. The known world class Cu-Mo deposit, Sarcheshmeh Porphyry deposit (central Iran) selected as the study area. The Hypogene zone of the deposit was chosen as the space in which estim...
