“…Nevertheless, it should be noted that slight peaks of the Fe 2 Zr intermetallic compound were also identified in the SHS product with 30 wt.% Fe addition, indicating that the full conversion of ZrC has not been achieved once the addition of Fe exceeds 30 wt.%. It is reported [14] that when synthesizing the transition-metal carbides, the full conversion of Zr and C to ZrC is generally difficult, and the formation of the binary phase even ternary phase is hardly avoided. However, in our work, there is no apparent presence for those phases except the designed ZrC and Fe unless the Fe addition in the mixtures exceeds 30 wt.%.…”

Layered stacking characteristics of ternary Zr-Al-C carbides were investigated using scanning transmission electron microscopy (STEM). Three previously unknown compounds, i.e., Zr 4 Al 3 C 6 , Zr 5 Al 6 C 9 , and Zr 7 Al 6 C 11 were identified. The present study extends the structural information of ternary Zr-Al-C ceramics. The influence of the thickness of the NaCl-type Zr-C slab on the elastic properties of ternary Zr-Al-C ceramics is discussed based on first-principles calculations. In addition, direct atomic-resolution observations illustrate the process for forming the unique layered crystal structures of ternary Zr-Al-C ceramics. These results also provide insights into the formation mechanism of layered ternary Zr-Al-C carbides.

“…1,2 However, its poor high-temperature chemical stability in air and intrinsic brittleness limit its applications.

“…4,6,7 In addition, its highly remained stiffness at high temperature ͑Young's modulus is 291 GPa at 1600°C͒ endows Zr 3 Al 3 C 5 a potential high-temperature structural material. 5,8 On the other hand, the theoretical elastic properties and thermal properties, such as Debye temperature, heat capacity, and thermal conductivity of Zr 2 Al 3 C 4 have never been reported. The structural difference between Zr 2 Al 3 C 4 and Zr 3 Al 3 C 5 is the thickness of ͑ZrC͒ m units between the Al 3 C 2 units, where m = 2 and 3, respectively.…”

The full set of second order elastic constants, bulk modulus, shear modulus, and Young's modulus of Zr 2 Al 3 C 4 were calculated and compared with those of Zr 3 Al 3 C 5 and ZrC. The experimentally measured Young's modulus and shear modulus are in good agreement with theoretical ones. The calculated Debye temperature from elastic constants of Zr 2 Al 3 C 4 is 830 K, which is slightly higher than that of Zr 3 Al 3 C 5 , and exhibits pronounced enhancement in comparison with that of ZrC. The highest Debye temperature of Zr 2 Al 3 C 4 is related with its highest specific stiffness, i.e., the stiffness-to-weight ratio. The heat capacity and thermal conductivity of Zr 2 Al 3 C 4 were measured by means of the flash method. The thermal conductivity of Zr 2 Al 3 C 4 decreases with increasing temperature, for instance the values at room temperature and 1600 K are 15.5 and 10.1 W/m K, respectively. The investigations provide information on elastic and thermal properties of Zr 2 Al 3 C 4 with promising high temperature applications.
