| Abstract Scope |
The demand for lightweight alloys with improved thermal management capabilities is getting higher with the increasing demand for electric vehicles (EVs). Hence, a comprehensive study is required to elucidate the relationship between microstructure and physical properties needed for EVs, such as conductivities and hardness of Al-alloys. We present a systematic experimental study on the effect of microstructural evolution of the Al3Ni eutectic phase in Al-Ni alloys on electrical and thermal properties. In addition, our experimental investigation on the role of microalloying elements, i.e., Ti, V, and Zr, and their propensity for segregation at the Al/Al3Ni interface will be presented. We also investigate the interplay between conductivities and mechanical properties as a function of microstructure. The research was sponsored by Oak Ridge National Laboratory, the Department of Energy, Vehicle Technologies Office, and Powertrain Materials Core Program. |
