| 英文摘要 | In this study, the formation, evolution, hardening and penetration behaviors of the copper-based jets were investigated based on SEM, EBSD, XRD, TEM techniques and finite element simulation methods. The results show that, compared with the penetration depth and hardness of the pure copper jets, the penetration depth of the Cu-Nd alloy jets has increased by approximately 22.2 %, and the hardness has increased by approximately 25.5 %. The increase in the jet penetration depth of the Cu-Nd alloy is mainly related to the fact that the addition of rare earth Nd element can simultaneously enhance the plasticity and strength of the alloy, and Nd element may react with O and S elements to release chemical energy. The hardening mechanisms of the Cu-Nd alloy jets mainly include: dispersion strengthening, grain refinement strengthening, dislocation strengthening and twinning strengthening. |
