Embodiment 1-4

[0032] The preparation of embodiment 1-4Al-Ga-In-Sn-Zn alloy

[0033] (1) The alloy composition is shown in Table 1:

[0034] The mass percent (wt%) of the aluminum alloy constituent elements of Table 1 Example 1-4

[0035]

[0036] (2) Preparation process:

[0037] Raw materials are various high-purity powders, Al, In, Sn, Zn particle diameters are all 99%, Ga is bulk material, added in liquid state (melting point: 29.76), purity >99%. Under the protection of argon, use a planetary ball mill for ball milling, and the ball milling parameters are as follows: the ball-to-material ratio is 5:1; the ball milling time is 12 hours; the rotational speed is 500 r / min.

Abstract

The invention relates to an Al-Ga-In-Sn-Zn alloy as well as a preparation method and an application thereof. The alloy is prepared from the following components by weight percent according to a mechanical alloying technique: 45-97wt% of metal Al, 1-20wt% of metal Ga, 0.5-15wt% of metal In, 1-10wt% of metal Sn and 0.5-10wt% of metal Zn. The alloy of the invention can directly react with water at the temperature of larger than or equal to zero DEG C so as to realize the effect of rapidly producing hydrogen; and hydrogen-producing rate reaches more than 90% of a theoretical value, and the reaction rate reaches 200ml / min.s, thereby meeting the dynamic powder requirement of hybrid electric vehicle travelling and greatly improving the utilization rate of gasoline.

Description

technical field [0001] The invention relates to an aluminum alloy material capable of providing power for automobiles, in particular to an Al-Ga-In-Sn-Zn alloy and its preparation method and application. Background technique [0002] Energy saving and new energy vehicles are the focus of the revitalization plan of the automobile industry. Faced with the increasingly severe energy situation and environmental protection pressure on a global scale, the world's major automobile producing countries regard the development of new energy vehicles as a major issue in improving industrial competitiveness and maintaining sustainable social and economic development. measure. In recent years, the utilization of new energy sources such as solar energy, hydrogen energy, wind energy, and geothermal energy has developed rapidly. Among them, hydrogen energy has the advantages of wide sources, clean and environmentally friendly, storable and renewable, and is regarded as the most promising dev...
