Abstract
The invention provides a method for manufacturing a foamed aluminum board. The method comprises the following steps of: putting titanium hydride powder containing 1 to 3 percent foaming agent into an aluminum or aluminum alloy pipe, sealing a plurality of aluminum or aluminum alloy pipes into which titanium hydride powder is filled in an aluminum or aluminum alloy box, performing mill processing and densifying, and foaming to prepare the foamed aluminum board. By the method, the defects that the pore structure is difficult to control in a casting method and preparation cost is high in a powder metallurgy method are overcome. Compared with an accumulative roll-bonding method, the method has the advantages that the foaming agent can be distributed uniformly, the pore volume can be controlled, the method is not limited by rolling reduction of a critical pass; by the method, the processing can be performed by a compound blank with a large section size, so that a foamed aluminum precursor can be manufactured under a low distortion temperature condition; and the method is convenient to operate and is low in cost.
