Aluminum magnesium boron-zirconium diboride dual-phase composite material and preparation method thereof
The invention provides an aluminum magnesium boron-zirconium diboride dual-phase composite material and a preparation method thereof, and belongs to the technical field of composite ceramic materials. The multiphase material is obtained by heating, pressurizing and carrying out in-situ reaction on zirconium oxide powder, boron carbide powder, aluminum oxide powder and magnesium oxide powder. The multiphase material has two phases of AlMgB14 and ZrB2, the density is up to 99%, the Vickers hardness is 38-42 GPa, the elastic modulus is 550-580 MPa, and the fracture toughness is 6.2-7.8 MPa.m < 1/2 >. The AlMgB14 and the ZrB2 simultaneously exist, so that the performance of the obtained aluminum magnesium boron-zirconium diboride double-phase composite material is far superior to that of single-phase ceramic.
本发明提供了一种铝镁硼‑二硼化锆双相复合材料及其制备方法，属于复合陶瓷材料技术领域。本发明的复相材料是由氧化锆粉、碳化硼粉、氧化铝粉和氧化镁粉经过加热加压原位反应后得到的。本发明的复相材料具有AlMgB14和ZrB2两相，致密度高达99％，维氏硬度为38～42GPa，弹性模量为550～580MPa，断裂韧性为6.2～7.8MPa·m1/2。本发明由于AlMgB14和ZrB2两相同时存在，得到的铝镁硼‑二硼化锆双相复合材料的性能远优于单相陶瓷。
