Аннотация

The article is devoted to the impact of carbon additives on densification and mechanical properties of ZrC/C hetero-modulus composites. In case of addition of small amount of carbon to ZrC residual porosity decreases, whereas higher carbon content leads to more than 3 vol % increase in residual porosity. With the increase of the carbon concentration up to 15 vol %, modulated decrease of elastic modulus and microhardness to 213 and 7.8 GPa, respectively, was observed. Moreover, increase in carbon content in ZrC/C composites enhance toughness of sintered materials. For example, KIC = 4.3 MPa m1/2 for ZrC and KIC = 7 MPa m1/2 for 3 vol % C. Ultimate strength under diametric compression exponentially decreased from 305 to 55 MPa with the increase of carbon concentration.
