Title: Radiation tolerance of M{sub n+1}AX{sub x} phases, Ti{sub 3}ALC{sub 2} and Ti{sub 3}SIC{sub 2}.

Abstract

During investigations of novel material types with uses in future nuclear technologies (ITER/DEMO and GenIV fission reactors), ternary carbides with compositions Ti{sub 3}AlC{sub 2} and Ti{sub 3}SiC{sub 2} have been irradiated with high Xe fluences, 6.25 x 10{sup 15} ions cm{sup -2} ({approx}25-30 dpa), using the IVEM-TANDEM facility at Argonne National Laboratory. Both compositions show high tolerance to damage, and give indications that they are likely to remain crystalline to much higher fluences. There is a visible difference in tolerance between Ti{sub 3}AlC{sub 2} and Ti{sub 3}SiC{sub 2} that can be related to the changes in bonding within each material. These initial findings provide evidence for a novel class of materials (+200 compounds) with high radiation resistance, while, significantly, both of these materials are composed of low-Z elements and hence exhibit no long-term activation.
