Fabrication of W-Al Energetic Structural Materials by Explosive Consolidation and Investigation of Its Quasi-Static Compression Properties

  • 摘要: 通过爆炸烧结法,采用不同粒度的W、Al混合粉末,成功制备了近乎致密的W-Al含能结构材料(ESM)。研究发现:冲击波压力是粉末致密化的主导因素,粉末粒径对烧结密度和微观结构的影响显著,W的粒径越小,颗粒团聚越明显,从而阻碍致密化,在致密块体中形成连续分布的W相。所制备样品的最大抗压强度和失效应变分别达到288 MPa和20%,材料的力学性能和断裂模式主要取决于连续相,Al相连续的ESM抗压强度低、塑性较好,呈轴向劈裂破坏;而W相连续的ESM则表现出脆性和高抗压强度,破坏模式为剪切破坏,与Al的低强度高塑性和W高强度脆性特性一致。
