摘要The microstructural evolution and the changes in mechanical properties of 7 MeV Xe26+-ion-irradiated Ti3SiC2 and Ti3AlC2 were investigated. At room temperature (RI), compared with Ti3SiC2, Ti3AlC2 showed a better resistance to irradiation damage, but underwent a more severe phase transition from a phase to beta phase. Rietveld refinement of X-ray diffraction patterns showed that the fraction of beta phase of Ti3SiC2 and Ti3AlC2 samples irradiated at RT to a dose of 2 x 10(15) ions/cm(2) are 28.05% and 57.42%, respectively. At a dose of 4 x 10(15) ions/cm(2), the crystal lattice of Ti3AlC2 was hardly damaged, while the lattice of Ti3SiC2 was heavily distorted. The hardness of Ti3SiC2 and Ti3AlC2 increased after RT irradiation, due to defect pinning effect. Moreover, both MAX phases irradiated at 600 degrees C shoved much better stabilities than after irradiation at RT. (C) 2015 Elsevier B.V. All rights reserved.
