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

Use Of High Temperature Die Material & Hot Dies For High Pressure Die Casting Pure Copper & Copper Alloys

Abstract Little use has been made of pressure die casting for the manufacture of copper or copper alloy parts due in large part to poor economics resulting from short die life in casting these high melting metals. A research program initiated in 1997 was driven by the promise of a signifi cant increase in the
