Abstract: A magnesium alloy composite material includes a magnesium alloy matrix, and a nanoparticle second phase material dispersed in the magnesium alloy matrix. The nanoparticle second phase material has an average particle size ranging from 1.0 nm to 100 nm. Preferably, the amount of the nanoparticle second phase material ranges from 0.05 wt % to 2.5 wt % based on total weight of the magnesium alloy composite material. With the addition of the nanoparticle second phase material to the magnesium alloy matrix, hardness can be increased to a relatively high level without significantly increasing density.

Abstract: A method of test includes the steps of preparing a sensing platform having an emitting electrode mounted at on one side thereof and a receiving electrode mounted on the other side thereof, wherein the sensing platform defines a sensing zone located between the emitting and receiving electrodes; placing a specimen on the sensing zone; emitting a surface acoustic wave from the emitting electrode, wherein the surface acoustic wave passes through the sensing zone and the specimen and then is received by the receiving electrode to be changed for its speed and phase by the change of material property of the specimen; and identifying the material property of the specimen according to the changed speed and phase of the surface acoustic wave to further infer the physical property of the specimen. In light of the steps, the surface acoustic wave can be employed for detection of the physical property of the specimen.
