Abstract: Compositions and methods for obtaining nanocrystal dispersed amorphous alloys are described. A composition includes an amorphous matrix forming element (e.g., Al or Fe); at least one transition metal element; and at least one crystallizing agent that is insoluble in the resulting amorphous matrix. During devitrification, the crystallizing agent causes the formation of a high density nanocrystal dispersion. The compositions and methods provide advantages in that materials with superior properties are provided.

Abstract: This duct heater assembly includes a duct section having upper and lower wall portions and opposed side portions. The upper and lower portions include end margin portions connectible to the end margins of conventional duct line section by "S" strip connectors. The side portions include C-shaped flanges connectible to the C-shaped flanges of conventional duct line sections by "C" strip connectors. One of the side portions incorporates a control box having an overhanging end spaced from the side wall of an adjacent conventional duct line section to accommodate the "C" strip connectors.
