Damping behaviors of as-cast and solution-treated AZ91–Ca magnesium alloys

The effects of solution treatment on the microstructure and damping capacity of AZ91 and AZ91–0.4%Ca alloys were investigated. In the as-cast state, the Ca addition contributed to the suppression of discontinuous β precipitation and to the formation of an Al2Ca phase; however, it reduced the amount...
