Abstract

In this study, 18-inch wheels, magnesium alloy AZ91D was developed and we compared overseas go on sale magnesium wheels and same specifications of the aluminum wheels mechanical properties. Prototype 18-inch magnesium wheels by a low-pressure casting method to achieve the same specifications of aluminum wheels and reduced 26% of the weight, the new edition of magnesium wheels compared to the same level of elongation, tensile strength, hardness. Casting and heat treatment process to improve future need to improve the yield strength is expected.

본 연구에서는 마그네슘 합금 AZ91D를 소재로 18인치 휠을 개발하고 동일사양의 알루미늄 휠과 해외 시판중인 마그네슘 휠과 기계적인 성질을 비교하였다. 저압주조 방식에 의해 18인치 마그네슘 휠 시제품을 제작하여 동일 사양의 알루미늄 휠 대비 26% 의 경량화를 이룩하였고, 신판 마그네슘 휠 대비 동등 수준의 연신율, 인장강도, 경도를 달성하였다. 향 후 주조와 열처리 공정 개선을 통해 항복강도 향상이 필요한 것으로 판단된다.
