        Effects of Ni, Co, B, and Ge on the Microstructures and Mechanical Properties of Nb-Ti-Si Ternary Alloys

        Qiang Huang,Yongwang Kang,Jinxia Song,Shiyu Qu,Yafang Han,Xiping Guo 대한금속·재료학회 2014 METALS AND MATERIALS International Vol.20 No.3

        Nb-Si in situ composites with a nominal composition of Nb-22Ti-12Si-X (at.%, X represents Ni, Co, B, or Ge)are prepared using non-consumable arc melting technology. The effects of the alloying elements on themicrostructures and mechanical properties are investigated. The Nb-22Ti-12Si ternary alloy consists of Nbss andNb3Si. A new phase of Ti2Ni or Ti2Co is introduced into the ternary system after adding Ni or Co. The addition of6% Ge promotes the formation of Nb5Si3 and creates significantly finer microstructures. The values of the hightemperature strength and room temperature fracture toughness of Nb-22Ti-12Si-6Ge are 566.33MPa and12.81MPa·m1/2, respectively, which are approximately 88.2% and 18.5% higher than those of Nb-22Ti-12Si(300.98 MPa and 10.81 MPa·m1/2). The addition of 3% B changed the morphological features and inducedthe appearance of large fine rosettes, which is favorable for restraining the crack propagation, and it also leadsto a 22.3% increase in room temperature fracture toughness compared with the Nb-22Ti-12Si ternaryalloy.
