Determining the microstructure and properties of magnesium aluminum composite panels by hot rolling and annealing

The researchers made magnesium aluminum composite panels by asymmetric metal packaging and studied rolling temperature, holding time, and high temperature heat treatment, such as short time and low temperatures over long periods of time parameters under the new preparation method. We tested the new magnesium aluminum composite panels' tensing properties and bending performance by using scanning electric mirror and EDS. It is concluded that the new magnesium aluminum composite panels' elongation is 24% under the tensile strength of 260 MPa. Regarding performance when compared with other methods, traditional magnesium aluminum composite panels' elongation is 10%, which shows its advanced nature. At the same time, bending performance test showed that the combination of the composite board has higher performance, offering the reference value for the preparation of magnesium–aluminum composite plate.
