Abstract
Microporous syntactic metal foams based on invar (FeNi36) alloy matrix and integrated S60HS micro hollow glass spheres were produced by means of metal powder injection moulding (MIM). The invar alloy was used in order to adjust thermal shrinkage behaviour of matrix and hollow spheres. Deformation behaviour and material properties such as compression and plateau strengths and specific energy absorption were determined using quasi-static compression and tensile tests. The foam structure was evaluated by means of metallographic sections and SEM/EDX. The results were related to processing parameters and to the micro-structure of the syntactic foams and compared to the behaviour of syntactic foams with different matrix alloys and micro hollow sphere types. Factors influencing the deformation behaviour of the syntactic foams are discussed.
