Amplitude-dependent internal friction in AZ31 alloy sheets submitted to accumulative roll bonding
Fine grained magnesium alloy AZ31 sheets were submitted to the accumulative roll bonding (ARB). After ARB, the microstructure of samples was refined, and the sheets exhibited pronounced texture. The amplitudedependent internal friction (ADIF) was measured at room temperature. Microstructure changes...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Fine grained magnesium alloy AZ31 sheets were submitted to the accumulative roll bonding (ARB). After
ARB, the microstructure of samples was refined, and the sheets exhibited pronounced texture. The amplitudedependent internal friction (ADIF) was measured at room temperature. Microstructure changes as the increased
dislocation density, grain size refinement, twins, and texture influenced the ADIF. A significant anisotropy of the
properties was observed. Experimental results are discussed on the base of physical mechanisms responsible for
internal friction. |
