“…7 at 550°C. Huang et al [2] observed the Al 20 CaTi 2 phase in Al foam with 1.5 wt% Ca heat treated at 540°C which confirms the findings of Nosko et al [1]. The notes on structure, stability, and solidification behavior of the Al 22 CaTi 2 compound published by Amsterdam et al [14] were not taken into account since any experimental details are missing.…”

“…Next to the matrix formed by (Al) solid solution, Al 4 Ca and Al 20 CaTi 2 phases were found in the microstructure of the Al-foam which was prepared by stirring the components at 680°C. Huang et al [2] observed presence of Al 20 CaTi 2 phase in Al-Cu foams with Ca additions prepared by introducing TiH 2 as a blowing agent. The phase was identified by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX).…”

Ternary Al-Ca-Ti alloy samples and diffusion couples Al 2 Ca-Ti were investigated using scanning electron microscopy with energy dispersive X-ray spectroscopy, X-ray powder diffraction, and metallographic analysis. The experiments turned out to be very difficult, as expected by this combination of elements, and adapted techniques were used. The results indicate that ternary solubilities of Ca in Al-Ti phases were not observed and no ternary phase was found in the ternary mid-composition range. The binary Ca-Ti and the ternary Al-Ca-Ti phase diagrams are developed for the first time. They are based on consistent thermodynamic calculation by combining the binary edge systems and incorporating the Al-rich Al 20 CaTi 2 phase.

“…However, for the aged Al-Sc-Zr foams, there is still some Al 4 Ca phase in the grain boundaries and the Al 4 Ca phase in the Al foam has been etching off after the same immersion condition, demonstrating the better corrosion resistance of the aged Al-Sc-Zr foams than the Al foam. Our recent research [11] indicates that the Cu element will be consumed by Ca element, forming fishbonelike eutectic Al-Cu-Ca phase which can be seen in Fig. 3(c).…”

“…The cellular Al-0.16Sc-0.08Zr foams were isochronally in 100℃ steps lasting 5h each, beginning at 200℃ and terminating at 600℃. For Al-5Cu foams, the Al-Cu-Ca phase [11] formed during the aging treatment has little effect on the mechanical property. The fabrication process of the cellular Al-based foams has been demonstrated particularly in [3].…”

Abstract-By using Ca particles as thickening agent and titanium hydride as blowing agent Cellular Al-0.16Sc-0.08Zr foams with a porosity of 72.5±0.5% were successfully fabricated by the melt-foaming method Isochronal aging treatments are beneficial to improve the mechanical properties and corrosion resistance significantly. Observation on the cell wall microstructure at 400℃ confirms the precipitation of nano-size Al 3 (Sc,Zr) particles that are coherent with Al matrix with an average radius of 4.1 nm. This suggests that these Al 3 (Sc,Zr) particles can inhibit the grain boundary sliding and dislocation movement, thus, strengthening the cell walls and increasing the compressive strength of the foams. In addition, the Sc 2 O 3 protective film over the detective surface improves the corrosion resistance of the aged Al-0.16Sc-0.08Zr foam.

To study the effect of calcium on the porosity, sphericity, and microstructure of Al‐Cu foams, a gradient calcium content (0.5, 1.0, 1.5, and 2.0 wt%) was added into aluminum A201 alloy (Al‐Cu alloy) for the cellular aluminum foam preparation via the melt foaming method (TiH2 was used as a bubbling agent). Thereafter, the porosity of the prepared Al foams and their pore size were found to increase, and the sphericity of pores tended to approach to unit with calcium addition. This phenomenon was then explained through the modified thermophysical properties (i.e., surface tension and viscosity) of A201 alloy melts caused by the calcium addition. After the microstructure analysis, a bunch of secondary phases in the A201+Ca alloy foams, e.g., CalAl2Si2, Al2Cu, and Al20CaTi2 as well as an eutectic phase with a great copper content Al8CaCu4 were detected by means of SEM/EDX and XRD.This article is protected by copyright.
