Abstract

Herein we report, for the first time, on the synthesis and structural characterization of the Zr-based MAX phase, Zr₃AlC₂, fabricated by reactive hot pressing of ZrH₂, Al, and C powders. The crystal structure of Zr₃AlC₂ was determined by X-ray diffraction and high resolution transmission electron microscopy to be the hexagonal space group P63/mmc. The a and c lattice parameters are 3.33308(6)Å and 19.9507(3)Å, respectively. The samples include the secondary phases ZrC and Zr-Al intermetallics as confirmed by quantitative electron probe microanalysis. The Vickers hardness, using a force of 30N, was measured to be 4.4±0.4GPa.
