摘要

MAX phase material is a layered ternary compound with the chemical formula Mn+1AXn.M represents the transition metal the A represents A-group element and X is the nitrogen or carbon.We take Ti3AlC2 as the sample.This material exhibits a combination of the attributes of both metals and ceramics[1].As a result,it has been considered as potential materials for use in current and future nuclear applications.Numerous researches have been focused on the phase transformation progress and anti-amorphization trait of this material[2;3].However,few researches have reported the behavior of vacancy defects after irradiation.We use the PAT and DBS technique to investigate this issue and try to find the relationship among the density of vacancy type defects,phase transformation,the irradiation fluence and temperature.
