摘要：
Explosive compaction by explosive detonation was investigated for rapidly solidified Al-Cu-Li-Mg powder. The densification, extent of interparticle bonding, microstructural modifications, and tensile properties were determined. The Al alloy powders were prepared by vacuum atomization with cooling ranges of 10**3 to 10**5 K per second. Variations in compaction pressure and detonation velocity were obtained by using different explosives and packing densities. The densification and interparticle bonding are correlated with explosive and powder parameters.
