Storage modulus (E') is the stored energy, and loss modulus (E'') is the energy dissipated during cyclic loading. In DMA, a sinusoidal stress is applied and the corresponding sinusoidal strain is measured.
Damping behavior was obtained at constant strain and at various frequencies of 0.1, 1, and 10 Hz from room temperature to 150°C under dual cantilever mode. Microstructural analysis was done using FESEM. Results demonstrated that the samples fabricated using powder metallurgy route exhibit high damping capacities and storage modulus.
Property data for over 1600 wrought and cast aluminum alloys and heat treatments is available and searchable by name, property values, or composition. Complete property data on aluminium includes density, hardness, shear strength, shear modulus, heat capacity, solidus, liquidus, elongation, Poisson's ratio, hardness, fatigue etc.
The damping behavior of pure aluminum fabricated via powder metallurgy has been investigated at two different heating modes (microwave and conventional). The aforementioned results have drawn the following conclusions. The storage modulus decreases with the rise in temperature for both CS and MS samples.
The fastest way to examine the database entries for the precise aluminum alloy of interest is to follow the link above to Search By Material Type and then select "Aluminum Alloy" in the drop down box under 'Nonferrous Metals'; this feature is reproduced below. (Click on the image to go there)
You can find typical values such as melting point, density, and thermal conductivity for typical aluminum alloys under the name Aluminum Alloys, General. Values for the pure element are found under the name Aluminum, Al. UNS numbers and ISO designations are supported for most aluminum alloys in MatWeb.
