| 1 | Microstructure,Mechanical,and Thermal Properties of B4C-TiB2-SiC Composites Prepared by Reactive Hot-pressing显示文摘B4C-TiB2-SiC composites with excellent properties were prepared by reactive hot-pressing using B4C,TiC,and Si powders as the raw materials.The phase transition process was investigated by heating the powder mixture to different temperatures and combined with XRD tests.TiB2 and SiC phases were synthesized through an in situ reaction,and the mechanical and thermal properties were improved simultaneously.Microstructure and mechanical properties were also studied,and the 60wt% B4C-21.6wt% TiB2-18.4wt% SiC composite showed a relative density of 99.1%,Vickers hardness of 34.6 GPa,flexural strength of 582 MPa,and fracture toughness of 5.08 MPa·m1/2.In addition,the values of thermal conductivity and thermal expansion coefficient were investigated,respectively. | CAO Yaoqin 何强龙 王为民 | 2020 | Journal of Wuhan University of Technology(Materials Science)2020，35，6： | 2 |
