A copper/Q235 steel/copper composite block with excellent bonding interfaces was prepared by explosive welding which a promising technique to fabricate laminates. The microstructure and mechanical properties of the were investigated via tensile-shear test, optical microscope (OM), X-ray diffraction (XRD), scanning electron (SEM), back-scattered (EBSD). results showed that shear strength upper-i...

With the development of ubiquitous information environment in metallurgical industry, driving type of metallurgical equipment systems is changing from energy-driven to information-driven. The problems of the metallurgical equipment information communication path intelligent planning are taken as the research object. Based on the cellular automata theory, the integrated framework of metallurgica...

Abstract Copper (Cu) wire has been extensively used in the semiconductors industry to replace gold because of its cost-effectiveness and high performance. However, it a massive challenge oxidation rate, hardness, susceptibility corrosion which is time-sensitive under environmental conditions. One attractive factors investigate electrolytes assembly process copper wire. these electrolyte chemica...

Since many household systems are fabricated out of metallic materials, changes to the household environment that accelerate corrosion rates will increase the frequency of failures in these systems. Recently, it has been reported that homes constructed with imported wallboard have increased failure rates in appliances, air conditioner heat exchanger coils, and visible corrosion on electrical wir...

Abstract This article presents a compositional analysis of metal artifacts from the Postclassic period ( a.d. 1100–1450) city Mayapan, Yucatan, Mexico. We document metallurgical production at R-183, an elite residential group and one most significant archaeological contexts associated with metalworking Mayapan. Salvage excavations in 1998 recovered small cache containing 282 copper bells, two m...
