TL;DR: In this article, it has been proved that the blowing gas to foam melted Mg is not CO 2 but CO, which is released from the liquid-solid reaction between Mg and CaCO 3.

TL;DR: In this paper, the influence of porosity and pore size on the quasi-static compressive properties of AZ31 magnesium alloy foams with closed-cell were successfully fabricated by melt foaming method using Ca and CaCO 3 as thickening and blowing agent, respectively, and the results showed that the yield strength, energy absorption capacity and ideality energy absorption efficiency were decreased with the increase in porosity.

TL;DR: In this article, closed-cell aluminum foams with different kinds and contents of ceramic microspheres are obtained using melt-foaming method, and the distribution and the effects of the ceramic micro-spheres on the mechanical properties of aluminum Foams are investigated.

TL;DR: In this article, closed-cell AZ31 magnesium alloy foams with different percentages of hollow ceramic microspheres (CMs) were synthesized using modified melt foaming method, and the effect of CMs on the foaming behaviors (specifically for porosity and pore size) and quasi-static compressive behaviors of Mg-based composite foams are characterized.

TL;DR: In this article, the carbon content of a 50-wt.% sulfur electrode was changed from 10 wt% to 40 wt.%, and the degradation rate and first discharge capacity depended on the composition of the sulfur electrode.
