Blades of a gas turbine are the main and most important parts of turbine machines that work in very difficult and complex conditions. Existence of discontinuities and defects in the structure of these parts cause sudden ...

Underwater friction stir welding (FSW) has been demonstrated to be an effective method to improve the mechanical properties of joints. To illuminate the characteristics of underwater FSW, the microstructural evolution and ...

Mesoporous silica SBA-15 was synthesized by liquid crystal method and then was functionalized by amino acid L-Cysteine in presence of N,N'-Dicyclohexylcarbodiimide (DCC) as coupling agent. The functionalized nanoporous ...

Knowledge of the measurable parameters in an electric arc furnace can effectively increase efficiency while declining energy consumption, hence leading to positive environmental consequences. This issue has been frequently ...

In this investigation, different amount of carbon and chromium content of Fe-Cr-C hardfacing alloys with the constant ratio of Cr/C=6 were used. These alloys were fabricated by GTAW on AISI 1010 mild steel substrates to ...

In this research, the influence of boron content on microstructure and dry sliding wear resistance of as-cast FeAl-based alloys was evaluated. The alloying process was carried out using vacuum induction melting and four ...

In this study, the shear spinning process and the rolling process on C11000 copper metal with a thickness reduction of 50% at room temperature were performed and investigated. In the shear spinning specimen, the grains are ...
