Abstract
A method for preparing a thin-walled composite pipe is provided, in which an AlN particle/zinc-aluminum 27 (AlN/ZA27) composite billet is subjected to multi-pass reciprocating extrusion at 250-350° C., and then loaded into a pipe extrusion die. The composite billet is heated with the temperature being in an ascending gradient distribution (within a range of 250-350° C.) along an extrusion direction from the billet to an outlet of the die, then kept a preset temperature for a period of time, and finally extruded at a rate of 0.1-0.5 mm/s to obtain the thin-walled composite pipe. A thin-walled composite pipe prepared by this method is also provided, including an AlN particle and a ZA27 alloy.
