The ternary layered MAX-phase materials combining the merits of both metals and ceramics,which could have high radiation damage tolerance and novel damage self-healing abilities due to their special structures,are considered as the candidate structural materials for next generation fusion reactor.In present work,110 keV helium implantation of Ti3SiC2 at room temperature was carried out with doses of.5×1016cm-2 and 1×1017cm-2 and the subsequent evolution of damage as well as the helium bubbles at different annealing temperatures were investigated using grazing incidence X-ray diffraction(GIXRD),Raman spectrum analysis and transmission electronic microscope(TEM).
