Microstructural Control of the Interface Layer for Strength Enhancement of Dissimilar Al/Cu Joints via Ni Addition during TIG Arc Brazing
نویسندگان
چکیده
Dissimilar metal joining between Al and Cu is effective for reducing the weight cost of electrical components. In this study, dissimilar lap pure to with an Al-Ni filler material was conducted using tungsten inert gas (TIG) arc brazing, effect Ni on joint strength associated microstructure intermetallic compound (IMC) layer at interface examined. The addition effectively increased interfacial joints. Regardless Ni, joints fractured in thick Al2Cu formed Al/Cu interface. However, reduced thickness IMC led formation Al7Cu4Ni particles weakest layer. Both reduction reinforcing particle are thought contribute increase

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Creep behavior and in-depth microstructural characterization of dissimilar joints
The 700 °C power plants currently under development will utilize Ni-base alloys such as alloy 617 for components to be operated at temperatures >650 °C. Due to economic reasons for components or parts of components which are subjected to temperatures <650 °C, 2% Cr or 9-12% Cr steels is used, depending on the required mechanical properties. This makes the dissimilar joining of Ni-base alloys an...
