Abstract
The invention discloses a preparation method of an in-situ ZrB2 particle reinforced magnesium-based composite. The key of the preparation method is preparation of the ZrB2 particle reinforced magnesium-based composite in situ. The preparation method of the magnesium-based composite comprises the following steps: adding 15-25vol.% Al-ZrB2 intermediate alloy in the smelting process of pure magnesium and applying high-energy ultrasound on the melt. The Al-ZrB2 intermediate alloy is prepared by a reaction system of Al, KBF4 and K2ZrF6; as the prices of KBF4 and K2ZrF6 are low, the production cost of the magnesium-based composite can not be increased; and the technology is simple, safe and reliable, is convenient to operate and has no three-waste pollution. The preparation method has the following technical effects: compared with the traditional Mg-Al series alloy material AM60, the second phase Mg17Al12 of the prepared ZrB2 particle reinforced magnesium-based composite changes from continuous netted pages to granules or short blocks, the reinforced phase is dispersed and distributed in the magnesium matrix and the macroscopic distribution is uniform.
