AbstractTi-doped Zr-2[Al(Si)](4)C-5 solid solutions were prepared by an in situ hot-pressing method and its effect on the mechanical properties and high-temperature oxidation behavior were investigated. The solid solutions show comparable hardness, strength, and fracture toughness with Zr-2[Al(Si)](4)C-5 except modulus, which decreases with Ti dopant content. The stiffness is maintained up to 1600 degrees C, which derives from the clean grain boundaries without glassy phases. The oxidation resistance of [Zr1-x(Ti)(x)](2)[Al(Si)](4)C-5 solid solutions at 1000 degrees-1300 degrees C is improved remarkably. The improved oxidation resistance is mostly due to the formation of a more protective oxide scale consisting of (Zr,Ti)O-2, Al2O3, and mullite.
