Embodiment 1
[0021] A method for preparing a foamed aluminum alloy shaped part with a uniform pore structure, comprising the following steps:
[0022]Step 1: Heat the aluminum alloy until it melts. Among them, aluminum alloys such as ZL101, ZL102, ZL111 series alloys, or cast aluminum-copper alloys, grades such as ZL201, ZL202, ZL205 series alloys, or alloys mainly containing copper or The deformed aluminum alloy mainly containing silicon can also be aluminum alloy containing magnesium, such as ZL301, ZL302, etc., and adjust the temperature to 630°C-680°C, and the temperature can be 635°C, 642°C, 650°C, 660°C, 665°C , 670°C, 675°C, adding titanium hydride equivalent to 0.5%-5% of the weight of the aluminum alloy, the amount of titanium hydride can be selected as 0.8%, 1.2%, 1.5%, 2.0%, 2.8%, 3.5%, 4.2% %, 4.7%, stirring at a speed of 500-800rpm for 60-500 seconds to disperse titanium hydride, for example, 500rpm, 600rpm, 700rpm, 750rpm can be selected, and the stirring time can be selected...
