In this paper, the microstructure and mechanical properties of the plain carbon steel-bronze interface of explosive welding and rolling were investigated. Explosive connection was done at two stop distances and with two different thicknesses of explosive material. Rolling of the welded composite was done at both ambient and preheated temperatures of 300 °C and with a constant thickness reductio...

In the present study, the effect of explosive welding stand-off distance on the structure and corrosion behavior of aluminum alloy 5083-copper joint is studied. The microstructure was examined by optical microscopy and scanning electron microscopy and corrosion behavior with poteniodynamic polarization tests and electrochemical impedance spectroscopy in a salt environment. Microscopic results s...

In the current research, the microstructural changes and corrosion behavior of two-layer Steel/Bronze sheets were investigated after the heat treatment of the explosive welding process. The heat treatment was performed at 600ºC for 16 hr. Dynamic potential polarization, electrochemical impedance spectroscopy, optical microscopy, and scanning electron microscopy analyses were used. Based on of t...

The concentrations of rare-earth elements (REEs) were determined with the aim of investigating the behavior of these elements in granitic rock, granitic soils and soils between rock and lichen in Shir-kuh of Yazd province. Rare earth element patterns of the P-rich granite were determined by the mixture of Eu-enriched feldspars, middle REEs to heavy REEs-enriched apatite and Light REEs-enriched ...

In this study, centrifugal casting process was used for producing Al/Mg bimetal. Molten Mg was poured at 700 oC, with 1.5 and 3 melt-to-solid volume ratio (Vm/Vs) into the 450 oC preheated solid Al rotating at 800, 1200, 1600 and 2000 rpm. Castings were kept inside the centrifuged casting machine and cooled down to 150 oC. Investigating the effect of melt-to-solid volume ratio showed that incre...
