| Abstract: | Zirconium diboridediboride(ZrB2)has a high melting temperature of 3245oC,a bulk hardness of 23GPaand excellent chemical stabilityat high temperature, which make it an excellent candidate for ultra-high temperature materials.However, unsatisfactory values of toughness are still obstacles for them to be used widely. In this paper,the methods of toughening of ZrB2-basedcomposites are introduced,such as SiC whisker or fiber, short carton fiber, nanosized SiC, ZrO2 Mo, Nb, BN and AlN etc. |
