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

Macro Porosity Formation: A Study in High Pressure Die Casting

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

Mesh resolution consideration for the viability prediction of lost salt cores in the high pressure die casting process

B. Fuchs and C. KörnerPublished Online:February 10, 2014pp 24-30 Abstract High pressure die casting is limited in its geometry since a lost core technology as with sand or low pressure casting is not state-of-the art. Using lost cores made from sodium chloride may be a solution for high pressure die casting. Due to the high dynamical forces
