Al Alloys and Manufacturing Processes for Lightweight Applications in Electric Vehicles

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

A heuristic approach to meet geometric tolerance in High Pressure Die Casting

A heuristic approach to meet geometric tolerance in High Pressure Die Casting

G.CampatelliA.Scippa Abstract In High Pressure Die Casting (HPDC), geometrical distortions usually happen during the cooling phase, due to the reduced cooling time and the high thermal gradient inside the product itself. This phenomenon affects most the thin walled products. The usual die design practice considers only the linear shrinking of the product during the cooling as a consequence of

Heat Treatment of High-Pressure Die Castings

고압 다이캐스팅의 열처리 Metallurgical and Materials Transactions A volume 38, pages2564–2574 (2007)Cite this article Abstract High-pressure die-cast Al alloys cannot normally be heated at high temperatures due to the presence of pores containing entrapped gases, which lead to the formation of surface blisters. It has been found that blistering can be avoided by using considerably shorter solution-treatment times
