具备绝热剪切敏感性的钨合金穿甲弹材料研究现状

Research status of WHA with adiabatic shear susceptibility

通过对绝热剪切在穿甲过程中作用的分析,比较了纯钨、钨合金和铀合金三类高密度弹芯材料的常规力学性能和穿甲性能,以及弹丸在穿甲时的破坏行为,重点介绍了近年来国外用铪、金属间化合物、SiO2复合材料、钛合金、高强钢为基体的钨合金及钨纤维/金属玻璃复合材料穿甲弹的研究进展情况,并指明了新型基体材料钨合金今后的研制方向。

By analyzing the influence of adiabatic shear susceptibility on penetration properties, the comparisons of mechanical properties, penetration properties and their failure behaviors among pure tungsten, tungsten alloy and uranium alloy are made. The emphases are placed on replacement of the nickel-base matrix with new matrix materials, such as hafnium alloy, intermetallics, SiO2 composite, titanium alloy, high strength steel. The development objective of WHA with adiabatic shear susceptibility is to achieve good mechanical properties and high adiabatic shear susceptibility.
