Abstract:

The microstructural mechanisms responsible for material damping are analyzed, with emphasis on those mechanisms responsible for the behavior in high damping alloys. A Cu-Al-Ni alloy is metallurgically characterized using transmission electron microscopy and differential scanning calorimetry. The microstructural characterization of the Cu-Mn alloy INCRAMUTE is refined using high resolution transmission electron microscopy and high resolution energy- dispersive x-ray spectroscopy. A qualitative theory for the strain dependence of damping capacity is given. Keywords Theses Stress strain relations Vibration.
