Preparation method of near-zero expansion Al-ZrW2O8 composite material
A preparation method of a near-zero-expansion Al-ZrW2O8 composite material comprises the steps that firstly, a ZrW2O8 micro-truss structure is prepared through a 3D ink-jet printing method, and a precursor of the ZrW2O8 micro-truss printing structure is a stable rheological body prepared from ZrW2O8 particles with the particle size range being 10-500 microns and a water-based or organic matter-based solution; the printed ZrW2O8 micro-truss is sintered in an air environment of 450-700 DEG C to obtain a ZrW2O8 skeleton structure, and the porosity of the skeleton structure is controlled to be 28-32%; and then aluminum or aluminum alloy melt is infiltrated into the ZrW2O8 framework within the temperature range of 400-750 DEG C, the Al-ZrW2O8 composite material of the ZrW2O8 framework structure is obtained, and the thermal expansion coefficient of the composite material within the temperature range of-100-100 DEG C is (-0.5-0.5) * 10 <-6 > K <-1 >.
一种近零膨胀Al‑ZrW2O8复合材料的制备方法，首先采用3D喷墨打印方法制备ZrW2O8微桁架结构，ZrW2O8微桁架打印结构的前驱体为粒度范围为10‑500μm的ZrW2O8颗粒与水基或有机物基溶液配置形成的稳定流变体；打印出的ZrW2O8微桁架在450‑700℃的空气环境中烧结获得ZrW2O8骨架结构，骨架结构的孔隙率控制为28‑32％；之后将铝或铝合金熔液在400‑750℃的温度范围内渗入ZrW2O8骨架，获得ZrW2O8骨架结构的Al‑ZrW2O8复合材料，复合材料在‑100～100℃温度范围内的热膨胀系数为(‑0.5～0.5)×10‑6K‑1。
