Heavy ion irradiation damage in Zr2AlC MAX phase

Autor: Mary E. Vickers, Kevin M. Knowles, Konstantina Lambrinou, H.H. Qarra, Sh. Akhmadaliev

Zr2AlC MAX phase-based ceramic material with 33 wt.% ZrC has been irradiated with 22 MeV Au7+ ions between room temperature and 600ºC, achieving a maximum nominal midrange dose of 3.5 displacements per atom. The response of the material to irradiati
