Abstract
Modern transportation applications, including aerospace, hybrid, and electrical vehicles, require improved lightweighting [1]. The improved lightweighting increases the mechanical and thermal loading that the castings experience [1]. Aluminum alloys are well suited to these applications due to their notable castability, high electrical and thermal conductivity, and potential for strength [2]. About 90% of commercial Al casting alloys rely upon Si and Mg alloying additions to ensure castability and strength [3, 4]. Unfortunately, the use of Si and Mg greatly reduce the electrical conductivity of the alloy [5, 6]. For example, the Al-Si high pressure die casting alloy has a low thermal conductivity of 100 W/mK [7]. This reinforcing the need for a new alloying system with high castability and conductivity.
