[0030] The invention provides an Al-Bi-TiB 2 The preparation method of composite material, comprises the following steps:
[0031] TiB 2p / Al composite material and Bi simple substance are heated and melted to obtain Al-Bi-TiB 2 melt; the TiB 2p TiB in / Al composites 2 The mass percentage of particles is ≤6%, and the Al-Bi-TiB 2 The mass percentage of Bi phase in the melt is ≤20%;
[0032] The Al-Bi-TiB 2The melt is cast after ultrasonic treatment to obtain the Al-Bi-TiB 2 composite material.
[0033] In the present invention, the TiB 2p TiB in / Al composites 2 The mass percentage of the particles is ≤6%, preferably 3-6%, more preferably 4-5%.
[0034] In the present invention, the TiB 2p The preparation method of / Al composite material comprises the following steps:
[0035] Mix and melt aluminum melt, borofluoride and titanate fluoride to obtain Al-TiB 2 Melt; the molar ratio of borofluorate and titanium fluoride is TiB 2 The atomic ratio of Ti element and B el...
