Platinum-doped aluminum alloy and preparation method thereof

Abstract

The invention relates to a platinum-doped aluminum alloy and a preparation method thereof. The platinum-doped aluminum alloy is prepared from components in parts by weight as follows: 100 parts of aluminum, 4-7 parts of magnesium, 0.5 parts of zinc, 6 parts of platinum and 7 parts of molybdenum carbide. The preparation method comprises steps as follows: adding 100 parts of the aluminum to a smelting furnace, and heating the aluminum until the aluminum is completely molten to form molten aluminum; sequentially adding 4-7 parts of the magnesium, 0.5 parts of the zinc, 6 parts of the platinum and 7 parts of the molybdenum carbide to the molten aluminum in Step 1), heating the mixture until the mixture is completely molten, and evenly mixing the mixture to obtain a mixed liquid; leaving the mixed liquid obtained in Step 2) to stand at the temperature of 580 DEG C for 13-19 h, and then transferring the mixed liquid into a casting mold of castings for casting. The platinum-doped aluminum alloy can overcome defects of the prior art, has higher toughness, moldability, hardenability and corrosion resistance and can be used as a high-end base material for efficient and deep processing.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a platinum-doped aluminum alloy and a preparation method thereof. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. [0003] However, the current aluminum alloys still have the following defects, such as: poor formability when melting and casting large ingots, and low hardenability during heat treatment, poor tempering resistance and cannot meet higher mechanical properties Requirements or some special properties (such as heat resistance, corrosion resistance), etc. These defects ha...

[0003] However, the current aluminum alloys still have the following defects, such as: poor formability when melting and casting large ingots, and low hardenability during heat treatment, poor tempering resistance and cannot meet higher mechanical properties Requirements or some special properties (such as heat resistance, corrosion resistance), etc.

These defects have seriously restricted the use of aluminum alloys to replace steel products and other strong materials and structures in the field of engineering technology.
