Improved design of automotive chassis components using ultra-fine ductile iron

Abstract

Automobile chassis parts are parts that require strength, and it has been difficult to use a rib structure for automobile undercarriage parts because a rib structure causes a chill structure, which reduces mechanical properties such as strength and toughness. In this study, a rib structure that can prevent the generation of chill structure is realized by using ultrafine ductile cast iron developed through joint research, which enables the use of the die casting method.
