High Porosity Metallic Glass Foam: A Powder Metallurgy Route
ثبت نشده
چکیده
A powder metallurgy route to the fabrication of metallic glass foam is introduced. The method involves consolidating metallic glass powder blended with blowing agent particulates to produce expandable precursors, capable of yielding foams with porosities as high as 86%. The foams are found to inherit the strength of the parent metallic glass, and to be able to deform heavily toward full densification absorbing high amounts of energy (>30 MJ/m). The content of this chapter was previously published in Applied Physics Letters 2007;91(16).
