Brillouin scattering is a nondestructive optical measurement that can test the elastic properties of materials precisely, i.e. elastic constant, viscosity, and etc. In this paper, we report a backscattering configuration to measure the elastic constants of a series of opaque Mg-Nd alloys in different aging time. The elastic constants, C11 and C12, increase sharply with the increase of aging time, while above 16 hours, C11 and C12 tend to be stable. It explains that aging time can improve elastic properties of Mg-Nd alloy, which indicates the change of texture, in a certain time range. At the same time, the theoretical spectrums of different aging times were also calculated, and they were compared with experimental spectrum to reveal the mechanism of effect on the elasticity.
