Interface associativity and energy absorption capability of anti-vibration porous Al-MM alloy core with iron alloy skin structures

The interface associativity and energy absorption capability of composite structure with anti-vibration porous Al-MM (cerium-rich mischmetal) alloy core and iron alloy skin were investigated. Porous aluminum core/iron alloy skin structures were fabricated considering an iron alloy tube as its shell and closed-cell porous Al-MM alloy as its core. A peeling experiment was carried out to calculate the capacity of interfacial bonding and a compression test was carried out to determine the energy absorption capability. The results showed that the addition of MM significantly enhanced both the interfacial bonding and the energy absorption capacity.
