Steven Richard Pires de OliveiraDissertação de MestradoOrientador na FEUP: Prof. Doutor Rui Jorge de Lemos NetoOrientador no INEGI: Doutora Inês Vieira de Oliveira Abstract The high pressure die casting process has undergone major advances in recent years, due to its increasing use in the automotive sector. Although aluminum alloys are the most widely used, the
JCampbellIRC in Materials, The University of Birmingham, Birmingham B15 2TT, UK Abstract A quantitative study of the factors influencing the variability of casting dimensions has been attempted. The variability of casting size limits the achievement of a finished (i.e. net) shape in one operation. The casting processes include lost wax, lost foam, sand casting, gravity
Katsunari Oikawa, Kazuhiro Sakakibara, Youji Yamada, Koichi Anzai Abstract The NaCl–Na2CO3 salt mixture is proposed as a water-soluble core material for aluminum die-casting processes. The mechanical properties and microstructures of NaCl–Na2CO3 samples prepared by gravity casting were investigated. The salt mixtures had superior properties compared to those of the pure salts. Plastic deformation occurred during compression tests at high temperatures
S. Cecchel, D. Ferrario The purpose of the present paper is to enhance and deepen the lightweight optimization in automotive, in particularfor commercial vehicles and buses. In detail, aim of this research is to develop a technically reliable and cost effectivesafety component for Light Commercial Vehicles (LCVs) in aluminum alloy. At this purpose, different solutions
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
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
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
