The effect of Zr doping on the structural property and helium behavior of Ti3SiC2 by first-principles study

Atomic Scale Insight into the Oxidation Mechanism of Nb/Ta‐Doped Ti3SiC2/Al2O3 Ceramics

“…[2][3][4][5] However, its relatively weak high-temperature oxidation resistance limits its application at elevated temperatures. [6] Numerous techniques have been developed to circumvent this limitation, such as doping M-or A-site elements to create solid solutions [7][8][9][10] and incorporating antioxidant components such as TiB 2 and SiC particles. [11][12][13] The effect of alloying elements on the oxidation resistance of Ti 3 SiC 2 has been extensively studied by Zhou et al They observed that doping Al in Ti 3 SiC 2 could enhance its oxidation resistance both in air [14] and hydrothermal [15] environments because of the formation of a continuous dense Al 2 O 3 layer during the oxidation process.…”
