Defense Intelligence Reference Document Metallic Glasses For Aerospace Applications

Defense Intelligence Agency · 30 pages · text from the file's own layer

The Defense Intelligence Agency issued this Defense Intelligence Reference Document (DIA-08-0911-012), dated 14 December 2009, as one of its FY 2009 advanced technology reports under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It reviews how metallic glasses are structured and processed, their mechanical properties, and metallic glass matrix composites. It concludes that dendritic composites could replace high-strength steels in some aerospace parts. It adds that wide aerospace use depends critically on developing new lightweight glass-forming alloys.

Figure 9, Materials Property Charts. (a) Strength and stiffness (bath normalized to density) of metallic glasses
(yellow) and dendrltic metallic glass matrix composites (red) compared with other materials. (b) Damage
tolerance. On this plot, the dashed lines represent contours of equal fracture energy. In both plots, polymer
composites (CFRP and GFRP) are represented by isotropic averages; continuous fiber composites can have greater
strength and stiffness in a direction parallel to the fibers. 39
