Abstract

This work investigates the compatibility of Zr₂AlC MAX phase-based ceramics with liquid LBE, and proposes a mechanism to explain the observed local Zr₂AlC/LBE interaction. The ceramics were exposed to oxygen-poor (C_O ≤ 2.2 × 10⁻¹⁰ mass%), static liquid LBE at 500 °C for 1000 h. A new Zr₂(Al,Bi,Pb)C MAX phase solid solution formed in-situ in the LBE-affected Zr₂AlC grains. Out-of-plane ordering was favorable in the new solid solution, whereby A-layers with high and low-Bi/Pb contents alternated in the crystal structure, in agreement with first-principles calculations. Bulk Zr₂(Al,Bi,Pb)C was synthesized by reactive hot pressing to study the crystal structure of the solid solution by neutron diffraction.
