摘　　要：通过对贫铀药型罩的静破甲实验，研究了不同热处理工艺，不同的材料纯度对聚能射流质量的影响。指出合适的淬火工艺对细化晶粒，消除或缓解择优取向起着重要作用；杂质在退火过程中向晶界偏析，使射流在伸长过程中出现晶界脆性断裂是影响射流质量的重要原因。In this paper,the influence of heat treatments and impurities on the performance of DU shaped charge jet was investigated by fire tests,These fire tests indicate that the prese nce of embrittling elements at grain boundaries which were formed by segregated impurities is a primary factor in the break up characteristics of the shaped charge jet,and a proper heat treatment can re-fine the DU grain size as well as eliminate the preferred orientation that developes during working of DU.
