Damping Mechanisms in Nanostructured Materials

Abstract

The objectives of the present ONR program may be described as follows: (1) Determination of the mechanisms controlling the synthesis of nanocrystalline Fe78B13Si9 from both elemental Fe, B, Si powders and Metglass 2605TCA (Fe78B13Si9) during the process of high energy ball milling; (2) Compaction of the milled powders by hot pressing and HIP; (3) Determination of mechanisms governing the thermal stability of the milled powders using differential scanning calorimetry; and (4) The study of the effects of high volume fraction of grain boundaries or interfaces on the damping behavior of the nanocrystalline bulk material.
