Gen IV nuclear reactors require new materials that can withstand harsher environments than in current reactors. The Mn+1AXn (MAX) phases are a group of layered machinable ternary compounds, where M is an early transition metal, A is a group 13 to 16 element, and X is C and/or N. These compounds possess mechanical properties atypical for ceramics, notably thermal conductivity and plasticity at high temperatures. Data about their irradiated properties are required to fully realize their potential. Research is thus ongoing to characterize their irradiated properties. Comparison of pre- and post-irradiated characterization of Ti3AlC2 and Ti2AlC irradiated up to 0.5 dpa and 700 C will be presented, including TEM analysis of microstructure, and electrical resistivity.
