摘要: 通过模压成形和高温烧结法制备了不同颗粒尺寸(20、50和90 μm)和淀粉含量(10 vol%、20 vol%和30 vol%)的Si预制体。采用高分辨率(1 μm)三维X射线断层扫描(3D μ-CT)技术，对Si颗粒预制体三维孔洞特征进行无损检测。研究制备了一种真空辅助压力浸渗设备，选用AlSi12合金浸渗Si预制体。在恒定温度(800˚C)下，以不同浸渗压力(300、400和500 kPa)和不同浸渗时间(3、5、8、11和15 s)浸渗Si预制体，并测量其浸渗高度。由于传统浸渗公式计算的浸渗高度与实验测得的结果存在差异，考虑孔洞三维特征参数的影响，提出了修正浸渗公式，公式计算的浸渗高度与实验测得的结果吻合。
Abstract: Si preforms with different particle sizes (20, 50 and 90 μm) and starch contents (10 vol%, 20 vol% and 30 vol%) were fabricated by compression molding and heat treatment. A high resolution (1 μm) three-dimensional X-ray micro-computed tomography (3D μ-CT) was used to nondestructively inspect pore characteristics in silicon particle preforms. A pressure infiltration equipment was made and calibrated to infiltrate the preforms with AlSi12 alloys. The preforms were infiltrated at constant temperature (800˚C) with different pressures (300, 400 and 500 kPa) and pressure-applied times (3, 5, 8, 11 and 15 s). And the infiltration heights were measured. Since the discrepancy between the infiltration heights calculated with the general infiltration equation and measured in the experiment was found, a modified infiltration equation was proposed considering the pore characteristic parameters from 3D μ-CT. The results of the modified equation showed good agreement with the experiment.
