    Notes: Al-Mg alloy foams were synthesized via conventional melt foaming method. Ca and TiH2 wereintroduced into molten Al-Mg alloys with different magnesium contents. The macrostructures ofresultant alloy foams were analyzed and correlated with compressive properties estimated bycompression test. It is shown that the pore structures observed in alloy foams degraded withincreasing Mg contents. This tendency was shown to be consistent with compressivecharacteristics of corresponding alloy foams. In detail, plateau strength was high for Al-1wt%Mgalloy foams, exhibiting a gradual decrease in plateau strength with increasing magnesium content

    Notes: A study was carried out to understand the relationship between the pore structure’s evolution ofAl alloy melt foam and its preparation variables, which include decomposition properties of titaniumhydride, the stirring foaming time and the holding foaming time. The results show that the foaming processof Al alloy melt can be inferred by the relation curves of decomposition quantity of titanium hydride andtime at a specific temperature. The porosity of Al alloy melt during stirring foaming period is kept constantwhile the pore number increases and pore diameter decreases, which is a new method of fabricating Al alloyfoam with a relatively low porosity and small pore size

    Comparative Study on TiH〈sub〉2〈/sub〉 and CaCO〈sub〉3〈/sub〉 for Fabrication of Mg Alloy Foams (2008)

    Notes: Aluminum alloy foams, new materials belonging to a special class of porous materials,have been prepared using melt foaming method. Silicon was chosen alloying element due to its lowdensity, high strength, effective casting and reduced shrinkage. Melt foaming method is cost-effectivemethod to fabricate metal foam. Usually, TiH2 is applied to blowing agent, but its cost is high. CaCO3is one of candidates to substitute TiH2 in the economic view-point. For the comparison of formability,Mg alloy foams were prepared by TiH2 and CaCO3. However, the decomposition temperature ofCaCO3 is higher than that of TiH2. This paper will be discussed on the possible usage of CaCO3 in theAl melt

    Notes: Fabrication of Aluminum foam with near net shape has been investigated by powdermetallurgy method and conventional pouring method. PM method is good for fabrication of near netshape foam, but it needs high cost compared with pouring method. More cost-effective methods areneeded to make near net shape al foam to be applied various field. Therefore, novel method forfabrication Al foam was researched in this paper. In order to prepare near shape Al foams withhomogeneous pore structures, the so-called upward foaming method was designed and applied. Byusing this method, two kinds of molds were designed, one is stainless mold used for melting andfoaming Al and another is the plaster mold with near net shape. The fabrication procedures of near netshape Al foam are as following: (1) a quantity of Al ingot was melted in the stainless mold; (2) Caparticles was added in the Al melt to increase its viscosity; (3) TiH2 was introduced in the thickenedAl melt to make melt being foamed; (4) the plaster mold was put on the stainless steel one to makeenlarging Al melt foam fill with the plaster one; (4) the plaster mold was removed and was cooled.In this study, in order to get near net Al foam with relative good pore structures, the plaster moldswere designed with three different upside styles and their effects on the pore structures (pore size,porosity and cell wall thickness) of Al foams were investigated. The results showed that the Al foamhad the relative good pore structures when the plaster mold with a void was applied

    Notes: Al-Mg alloy foams containing different Mg contents were synthesized via a conventionalmelt foaming method. The surface structures of pores formed in resultant foamed alloys wascharacterized by scanning electron microscopy and x-ray diffractometer. It was found that the porestructures were deteriorated with increasing Mg contents, while the percent porosities did not varywith increasing Mg contents, about 90% and 3~5 mm in pore size. The detailed microstructuralexamination conducted on increasing Mg containing alloy foams revealed presence of various oxideparticles on the surface of individual cells, including MgAl2O4 particles in a form of fine spinel; itssmall amount for Al-1wt%Mg alloy foam but relative high amount of Al-4wt%Mg one. Thissuggested the negative effect of MgAl2O4 on the stable pore and thus cell structures in correspondingalloy foams. The possible mechanism associated with MgAl2O4 formation was discussed in thepresent study

    Fabrication and Characterization of Slag Fiber by Melt Extraction (2007)

    Notes: The influence of wheel speed and melt temperature on the surface characteristics of slagfibers were examined in mineral fibers synthesized from the steel-making slag, using a modified meltextraction method, i.e. melt spinning. The synthesized fibers were characterized by opticalmicroscope and scanning electron microscopy. It was found that the wheel speed of 700 rpmgenerated better quality of mineral fibers in terms of diameter and length. This was attributed to therelative extent of contact width between the flowing melt and the rotating wheel. The thickness of theslag fibers were also decreased with increasing the slag melt temperature due mainly to significantdecrease in the viscosity of the slag melt. In addition, the lower melt temperature caused an increase innumber of shots plus the mineral fibers
