| 摘 要： | 烧结态93W、98W钨合金复合模拟弹,在爆炸洞中静爆,分别进行破片回收和穿靶试验,分析破片分布特征和穿靶效应.结果表明,93W的破片质量在0.1～3.0g之间,破片大小不均,回收率较高.而98W破片集中分布在0.1～0.5g之间,98%破片形状都近似等轴状,回收率较低.93W、98W合金复合模拟弹穿靶结果相近,对于2mm普通钢板靶,最小穿靶破片质量在0.1g左右.93W破片断口以沿晶断裂为主;98W破片断口则是沿晶和穿晶的混合断裂.

| Abstract: | The fragment mass, amount distribution and penetrating behaviour of 93W and 98W under explosive loading were investigated. The mass of 93W fragments ranged from 0.1g to 3.0g. The mass and shape of 93W fragments are not well-distributed, but those of 98W are. The mass of 98W fragments has a concentrated distribution from 0.1g to 0.5g and over 98% of the fragment shapes are close to isoaxial. Failures at the tungsten-matrix interface are main on fragments of 93W. However, 98W fragments had a large proportion of transgranular cleavage. |
