Structure and properties of zrc/c high temperature heteromodulus composites
It has been studied carbon addition on densification and mechanical properties of ZrC/C heteromodulus composites. I was shown that for small amount of carbon to ZrC the residual porosity are decrease, for higher carbon content, more 3vol.% the residual porosity increase. Beside this, increasing of carbon content in ZrC/C composites increase the toughness of sintered material. For example, КIC = 4.3 MPa*m1/2 for ZrC and for 3 vol.% C КIC = 7 MPa*m1/2. For 15 vol.% of carbon toughness was smallest and equals 5.3 MPa*m1/2.
