High temperature deformation behavior of closed cell ZnAl27 hybrid foam made through stir casting technique
TL;DR: In this article, a closed cell ZnAl27 hybrid foam was synthesized through stir casting technique using CaH2 (0.5 wt%) as foaming agent and cenosphere particles were used as thickening agent and to create microporosity into the final structure.

Effect of cenosphere size on the dry sliding wear behaviour LM13-cenosphere syntactic foam
TL;DR: In this article, the dry sliding wear behavior of LM13 cenosphere syntactic foam has been examined at varying applied pressures and sliding speeds, and it has been observed that the coefficient of friction, the frictional heating and the wear rate decrease with decrease in cenospheric size.

On the microstructure of ceramic hollow microspheres
TL;DR: In this paper, the microstructure of the ceramic hollow microspheres as reinforcing element was investigated, and the results showed that the Al2O3 and SiO2 distribution was not equal; the Al 2O3 phase was embedded in the surrounding mullite and Si O2 phase in the form of needles.

Experimental study of energy absorption in a close-celled aluminum foam under dynamic loading
TL;DR: In this paper, the authors determined the minimum height of aluminum foam specimens for compression test at a quasi-static strain rate by comparing the specific yield stress (i.e., yield stress per (relative density),sup 3/2}) of the foam with other data previously reported.

High strain rate compression of closed-cell aluminium foams
TL;DR: In this article, the compressive deformation behavior of open-and closed-cell aluminum foams was assessed under static and dynamic loading conditions, and high strain rate experiments were conducted in a laboratory using a split Hopkinson pressure bar system at strain rates ranging from 400 to 2500 s−1.

Plasticity and Damage in Aluminum Syntactic Foams Deformed under Dynamic and Quasi-Static Conditions
TL;DR: In this paper, synthetic foams were fabricated by liquid metal infiltration of commercially pure and 7075 aluminum into preforms of hollow ceramic microspheres, which exhibited peak strength during quasi-static compression ranging from −100 to −230 MPa, while dynamic compression loading showed a 10-30% increase in peak strength magnitude, with strain rate sensitivities similar to those of aluminum-matrix composite materials.
