초록

[ $CaCO_3$ ]를 발포제로 사용하여 균일한 기공구조를 가지는 AZ91과 AM60 마그네슘 합금의 발포 금속을 주조법을 통하석 제조하였다. 발포 금속의 제조가 가능한 이유와 발포 마그네슘 합금의 기공구조가 연구를 통하여 논의되었다. 마그네슘 합금의 용탕은 $CaCO_3$의 분해 거동에 영향을 미친다. 제조된 AZ91 마그네슘 합금의 발포 금속은 높은 기공률과 큰 기공의 크기를 가졌으며, 발포 금속들 중에서 상대적으로 쉽게 발포되는 것으로 판단된다.

For the first time AZ91 (MgAl9Zn1) and AM60 (MgAl6) Mg alloy foams with homogeneous pore structures were prepared successfully via melting foaming method by using $CaCO_3$ powder as blowing agent. The possible foaming mechanisms and pore structures of these Mg alloy foams were discussed and investigated. The results show that Mg alloy melt can affect $CaCO_3$ decomposition behavior and AZ91 Mg alloy is relative easy to be foamed into metal foam with high porosity and big pore size.
