| 摘 要： | 采用了液态浸渗法制备了Al2O3短纤维和SiC颗粒混杂增强镁合金复合材料.研究了浸渗压力对镁基复合材料力学性能和微观组织的影响.研究表明,当浸渗压力从0.4 MPa增加到60 MPa的过程中,由于组织的密实使得力学性能上升;随着浸渗压力的增加,将导致预制体受到压缩变形,纤维折断,从而导致综合力学性能下降.

| Abstract: | Liquid infiltration was used to prepare magnesium matrix composites reinforced by Al-2O-3 short fibers and SiC particles. Effects of pressure during liquid infiltration on the mechanical properties and microstructures were also investigated. Results show that when the pressure increased from 0.4 MPa to 60 MPa, the mechanical properties of magnesium matrix composites were increased due to the densification of microstructure. With further increasing pressure, because the preformed body was subjected to compression and short fibers were broken down, the mechanical properties of magnesium matrix composites were decreased. |
