摘要多功能含能结构材料是一类具有一定强度而且在冲击作用下能够发生化学反应释放能量一些亚稳态金属、金属化合物、非金属中的一种或几种组成的混合物。由于这类材料同时具有结构强度和冲击反应释能特性，在高效毁伤与防护方面有着重要的应用前景。本文主要研究了典型的金属类含能结构材料钨锆合金的制备工艺对于合金性能和表征的影响。分别按照5种材料配比，3种烧结温度，三种冷却降温速率以及晶须增强四种可能影响材料性能的因素，制备出了10组钨锆含能材料试件，然后对试件进行了扫描电镜分析，观察了试件表面形貌特征，分析了烧结温度对于合金晶体组成的影响。同时，对试件进行了准静态压缩实验，利用matlab程序分析了实验得到的应力-应变关系，得到真实的应力-应变曲线，从而分析了各种因素对材料性能的影响。实验结果发现：在W含量为45.4%，Zr含量为54.6%时，烧结温度为1490℃，冷却速率为6℃/min时，钨锆合金屈服极限最高，达到了240MPa，合金的性能较好。20552

Title Study On the Factors that Affecting Properties and Characterization of Multifunctional Energetic Structural Materials
Abstract
Multifunctional Energetic Structural Materials is a class of a mixture which with certain strength and chemical energy release under impacting. It consists of one or several metastable metallic, non-metallic, metal compound. Because this kind of material has the characteristics of structure strength and impulse response energy release, it has an important application foreground in efficient damage and protection. This paper mainly studies the effect of the preparation process to the Tungsten, Zirconium alloys' properties and characteristics, which is a kind of typical metal energetic structural materials. According to the five kinds of material ratio, three kinds of sintering temperature, three kinds of cooling rate and whisker reinforced four factors that may affect the properties of the materials, we prepared ten sets of energetic material specimens of Tungsten, Zirconium alloys, and then the specimens were analyzed by scanning electron microscope, we observed surface morphology characteristics of the specimens and analyzed the effect of sintering temperature on the crystal. At the same time, the specimens quasi-static compression tests were conducted, we analyzed the stress-strain relationship by using Matlab program, get the true stress-strain curve, so as to analyze the influence of various factors on the properties of materials. Experimental results show that: when the content of W is 45.4%, the content of Zr is 54.6%, the sintering temperature is 1490 ℃, the cooling rate of 6 ℃ /min, the Tungsten, Zirconium alloys has a better limit yield, reached 240MPa, the alloy has a better performance.
