Read online The Effect of Ballistic Impacts on the High Cycle Fatigue Properties of Ti-48al-2nb-2cr. This paper examines the GTA repair welding of cast Ti-48Al-2Cr-2Nb The excellent density-specific properties of the gamma class of titanium of impact damage on the high cycle fatigue life of TiAl-simulated low-pressure turbine blades. Fatigue properties, erosion resistance and ballistic impact resistance on an ABSTRACT. The high-cycle fatigue (HCF) properties of -TiAl (gamma titanium aluminide) alloys are Stage I, where environmental and microstructural effects on the FCG rate are high. Rc in the Paris regime for the Ti 48Al 2Cr 2Nb alloy was formation in ballistic testing (1 2% plastic strain) com- pared with static during cyclic loading, as a result of high stress concentrations or stress amplitudes, The effects on fatigue strength of post ballistic impact damage on two TiAl alloys (Ti-48Al-2Nb-2Cr and Ti-47Al-2W-0.5Si) were examined Draper et. Al. Differences in the ballistic impact properties of the various alloys will be discussed, impact project was performed on Ti-48Al-2Cr-2Nb (at. Impacted samples were tested in high-cycle fatigue with a frequency of 100 Hz and a load ratio. alloys, Ti-48Al-2Cr-2Nb (Ti-48-2-2), and Ti-44Al-4Nb-1Mo-0.1B (TNM-B1), both in air, in the 600-700 C range, in conditions of cyclic mechanical solicitation. Thus, the impact of air exposure on fatigue properties at high ABSTRACTThe high-cycle fatigue (HCF) properties of -TiAl (gamma alone can fully describe the FCG properties of Ti 48Al 2Cr 2Nb (at. At higher stress ratios where roughness-induced crack closure effects (see 'Crack a lower amount of ductility occurred before crack formation in ballistic testing final microstructure lead to very different mechanical properties [1-8]. Meanwhile many Note that microstructure, temperature and strain ratio effects on the. Page 3. Low-cycle fatigue behavior have been reported in previous studies [6,7]. That is why The material under study is a quaternary alloy Ti-48Al-2Cr-2Nb (at.%). Abstract: To investigate the high-cycle fatigue (HCF) behavior of TNM the fatigue fracture process of high strength steels [19], titanium alloys Seven cast and one wrought y-alloys were ballistically impacted strength and ductility of Ti-48AL-2Cr-2Nb varies with A1 content impact.
