Abstract

The invention provides a microcrystalline titanium based fiber reinforced aluminum alloy composite wire material and a preparation method thereof. The material has good performance. The preparation method is simple in process, low in production cost and suitable for industrialized production. The composite material takes the aluminum alloy as the matrix and the microcrystalline titanium based fibers are distributed on the matrix. The particle size of the microcrystalline titanium based fibers is 0.5-10mu m. The microcrystalline titanium based fibers account for 20-30% of the composite wire material by volume. The aluminum alloy matrix comprises the following chemical components in percentage by weight: 3-5% of Mg, 0.003-0.09% of Cu, 0.1-0.9% of Pb, 0.003-0.09% of Gd, 0.003-0.09% of Pr and the balance Al.

Description

1. Technical field [0001] The invention belongs to the field of metal materials, and relates to a microcrystalline titanium-based fiber-reinforced aluminum alloy composite wire material and a preparation method thereof. 2. Background technology [0002] At present, in the field of metal materials, more and more attention has been paid to the role of composite material wires. [0003] Application No. CN101058866 relates to a preparation method of an aluminum-based composite material. The method is to add 0.15 to 0.35 wt% of the total amount of CeO to the alloy after the aluminum-based alloy is completely melted at 750°C 2 Powder stirring alloying treatment step, followed by heat preservation step, adding reinforcement to the alloy melt during heat preservation, stirring step, then sending it into a vacuum furnace for vacuum degassing step, and then casting to obtain an aluminum matrix composite material billet step, wherein the reinforcing body is made of carbon fiber, and t...
