Microstructure and compressive deformation behavior of 2014 aluminium cenosphere syntactic foam made through stircasting technique

The present paper deals with manufacturing and characterization of aluminium syntactic foam which was fabricated through stir casting technique. The developed foam was made of 2014 aluminium alloy and 25 vol% of cenosphere particles. The quasi-static compression behavior was studied experimentally at a strain rate of 0.001/s. The fabricated foam shows high strength and a plateau region under compression behavior. The young’s modulus, yield stress, plateau stress and densification strain were quantified and presented. The fabricated foam was also characterized in terms of microstructure to show the cenosphere distribution in aluminium matrix. The microstructure results confirms uniform distribution of cenosphere particle.
