摘要：

Aluminum alloys for high-pressure die casting (HPDC) usually contain sufficient quantities of dissolved iron to reduce die wear and soldering. Unfortunately, iron reduces ductility, making the product unsuitable for crash-resistant automotive components. Recent improvements in machine design and new alloys allow the production of high ductility, structural HPDC components. This paper details the chemical and metallurgical factors underlying this development .
