Achieving high-strength metallurgical bonding between A356 aluminum and copper through compound casting
Bakke, Aina Opsal; Arnberg, Lars; Li, Yanjun (Peer reviewed; Journal article, 2021)Due to stable surface oxides on the solid copper surface and the ease of forming Al2O3 films at the aluminum melt surface, it is difficult to achieve high-strength metallurgical bonding between the two materials through ... -
Effect of Surface Treatment and Preheating Temperature on Compound Casting of Aluminium Alloy A356 onto 6060 Inserts
Grasmo, Siren (Master thesis, 2019)For bilindustrien er det viktig å studere ulike metoder for å redusere kjøretøyvekt, da dette reduserer bensinforbruk, noe som vil ha både økonomiske og miljømessige fordeler. Hybridstøpning er å støpe et flytende materiale ... -
Effects of Surface Treatment on Hypoeutectoid Steels and Commercially Pure Copper in a Compound Casting Process with Aluminum A356 Alloy
Bakke, Aina Opsal (Master thesis, 2017)Evidence of climate change has caused industries worldwide to start measures towards reducing greenhouse gas emission. The automotive industry is a large contributor to emission and has therefore demanded production of ... -
Formation and evolution of the interfacial structure in Al/steel compound castings during solidification and heat treatment
Bakke, Aina Opsal; Arnberg, Lars; Løland, Jan-Ove; Jørgensen, Svein; Kvinge, Jan; Li, Yanjun (Peer reviewed; Journal article, 2020)In this work, Al7SiMg/steel compound castings were produced through a low-pressure die casting process. All steel inserts were galvanized, where half of them were flux-coated to further improve the wettability and remove ... -
Interfacial microstructure formation in A356/steel compound castings using metal coating
Bakke, Aina Opsal; Nordmark, Arne; Arnberg, Lars; Li, Yanjun (Peer reviewed; Journal article, 2020)Compound castings between aluminum and steel have great potential for applications in the automotive industry. However, due to large differences in thermal and mechanical properties between steel and aluminum, and the ... -
Interfacial Microstructure Formation in Al7SiMg/Cu Compound Castings
Bakke, Aina Opsal; Løland, Jan-Ove; Jørgensen, Svein; Kvinge, Jan; Arnberg, Lars; Li, Yanjun (Peer reviewed; Journal article, 2020)Compound casting is an attractive approach to create multi-material components and thus reduce the overall weight, while maintaining both the functional and mechanical properties. In this work, Al7SiMg alloy/copper compound ... -
Microstructure in A356/AA6xxx after bimetallic casting with flux coating
Bakke, Aina Opsal; Arnberg, Lars; Li, Yanjun (Journal article; Peer reviewed, 2019)This work focuses on bimetallic casting between A356 alloy melt and profiles of AA6xxx wrought aluminum alloys through a gravity casting process, with the aim to improve the component's mechanical properties. However, ... -
Sn-Aided Joining of Cast Aluminum and Steel Through a Compound Casting Process
Bakke, Aina Opsal; Nordmark, Arne; Arnberg, Lars; Li, Yanjun (Peer reviewed; Journal article, 2021)Obtaining a strong bond between aluminum and steel is challenging due to poor wettability between aluminum melt and steel and brittle intermetallic phases forming in the interface. In this research, a novel coating method, ...
