Method for preparing aluminum-based TiB2 composite material through in-situ reaction salt melting method

The invention discloses a method for preparing an aluminum-based TiB2 composite material through an in-situ reaction salt melting method. The high-strength soluble aluminum-based TiB2 composite material prepared through the in-situ reaction salt melting method comprises 50-98 wt.% of Al, 1-30 wt.% of Zn, 0.1-10 wt.% of Sn, 0.1-5 wt.% of Ga and 0.1-5 wt.% of In. The two kinds of salt including K2TiF6 and KBF4 are evenly mixed according to a certain molar ratio to be added into uniform melt, a series of chemical reactions are generated, and evenly-distributed particle reinforced bodies TiB2 aregenerated in the aluminum alloy melt. The soluble aluminum-based TiB2 composite material treated through the method is more refined and has excellent mechanical performance and machine performance, and the high-strength soluble aluminum-based TiB2 composite material can be obtained and is widely applied to the oil and gas field fracturing construction process. 种用原位反应熔盐法制备铝基TiB复合材料的方法，利用原位反应熔盐法制备的高强可溶解铝基TiB复合材料中Al含量为50-98w
