Abstract
The invention discloses foamed aluminiumalloy and a preparing method thereof. The foamed aluminiumalloy comprises, by weight, 70-80 parts of aluminum, 10-30 parts of magnesium, 15-25 parts of zinc, 5-10 parts of zirconium. The preparing method comprises the steps that a, the aluminium, the magnesium and the zinc are made into powder respectively, and the fineness of the powder is 200-300 mesh; b, the aluminium powder, the magnesiumpowder and the zinc powder are mixed and heated to 600 DEG C; c, heating of the mixed powder continues until the temperature reaches 650-700 DEG C, and a foaming agent is added into the mixed powder and stirred; d, the temperature is kept for 5-8 minutes; e, the mixed materials are rapidly cooled to 200-300 DEG C and then cooled naturally. The foaming agent is zirconiumhydride. The foamed aluminium alloy has the advantages that air holes are distributed evenly, so that the strength of alloy materials is guaranteed, the foamed aluminium alloy is good in soundproofing effect, high in heat preservation effect and easy to popularize.
Description
technical field [0001] The invention relates to a method for preparing metal materials, in particular to a foamed aluminum alloy and a method for preparing the same. Background technique [0002] Porous metal means that there are a large number of directional or random pores dispersed in the metal. Due to the different design requirements for the holes, the holes can be foam type, lotus type, honeycomb type and so on. Porous metal materials can also be divided into two categories according to the shape of their pores: independent pore type and continuous pore type. The independent type material has the characteristics of small specific gravity, good rigidity, specific strength, good vibration absorption and sound absorption performance; the continuous type material not only has the above characteristics, but also has the characteristics of permeability and air permeability. Because porous metal materials have the characteristics of structural materials and functional mater...
