Embodiment 1
[0026] A method for preparing a composite energetic fragment of an outer metal base and an inner polymer base, the specific steps are as follows:
[0027] (1) First prepare the outer metal-based hollow cylindrical specimen;
[0028] Weighing and powder mixing: the mass ratio of each component is: tungsten powder / zirconium powder=30 / 70, that is, 30g of tungsten powder and 70g of zirconium powder are weighed. Put it in a full-range planetary ball mill and mix for 1h, and mix well;
[0029] Molding: Put the uniformly mixed tungsten powder / zirconium powder in a hollow cylindrical mold for compression, the pressure is 30MPa, the pressurization rate is 30N / s, the pressure holding time is 4min, the pressure release rate is 30N / s, and the mold is released after the pressure release. obtain molded parts;
[0030] Sintering: Put the above-mentioned molded parts after demoulding in a sintering furnace for sintering, use an argon atmosphere during the sintering process, the sintering te...
