Notes:
Ti〈sub〉3〈/sub〉SiC〈sub〉2〈/sub〉 has been widely investigated for their intriguing physical and mechanical properties [1]. In the past decades, dense and pure polycrystalline Ti〈sub〉3〈/sub〉SiC〈sub〉2〈/sub〉 has been fabricated by some techniques [1,2]. Studies on deformation and fracture behavior at elevated temperature showed that Ti〈sub〉3〈/sub〉SiC〈sub〉2〈/sub〉 exhibited substantial plasticity with high strength [3]. It is pointed out that Ti〈sub〉3〈/sub〉SiC〈sub〉2〈/sub〉 can be possibly used for some contact applications, such as bearings, for its relative high compression strength, self-lubricating and machinability [1]. In the present paper, fatigue crack-growth rates and Hertzian contact damage of Ti〈sub〉3〈/sub〉SiC〈sub〉2〈/sub〉 were studied. Shielding ability of Ti〈sub〉3〈/sub〉SiC〈sub〉2〈/sub〉 was investigated specially in the small crack region. Damage evolution and strength degradation under Hertzian contact were studied to reveal damage behavior and mechanisms in Ti〈sub〉3〈/sub〉SiC〈sub〉2〈/sub〉
