Development of High-Ductility and Low-Hot-Tearing-Susceptibility Non-heat Treatment Al–Mg–Mn-Based Die Casting Alloy for Automotive Structural Parts

Development of High-Ductility and Low-Hot-Tearing-Susceptibility Non-heat Treatment Al–Mg–Mn-Based Die Casting Alloy for Automotive Structural Parts

International Journal of Metalcasting (2023)Cite this article Abstract Non-heat-treated Al–Mg-based die casting alloys have been developed for the structural parts of automobiles. In previous studies, alloy compositions with at least 1.0%Si have been proposed to reduce the hot tearing susceptibility (HTS). On the other hand, the increase in the Si content reduces the ductility. For some

Al Alloys and Manufacturing Processes for Lightweight Applications in Electric Vehicles

Abstract. Due to increasing environmental concerns, battery-powered electric vehicles (BEV) have gained popularity in the automotive for the past few years. An induction motor is an essential component of the propulsion system in integrated BEVs working on different operating conditions [1]. Since a rotor of the induction motor is configured with an electrical sheet, a

Macro Porosity Formation: A Study in High Pressure Die Casting

David Blondheim Jr. & Alex Monroe Abstract Porosity formation in high pressure die casting (HPDC) impacts mechanical properties and casting quality. Much is published regarding micro porosity and its impact on mechanical properties, but there is limited research on the actual formation of macro porosity. In production applications, macro porosity plays a critically important role in casting
