1. 6. Fretting fatigue life analysis for a gas turbine compressor blade-disk material combination

   University essay from KTH/Hållfasthetslära

   Author : Elham Khoramzad; [2020]
   Keywords : ;

   Abstract : In order to analyse fretting fatigue life of dove-tail joints used in the compressor stage of a gas turbine, experimental study of different material combinations was conducted using rectangular fatigue specimen and bridge type pads. Specimen and pad interaction was simulated numerically and obtained results was used as input for 2 different crack propagation life prediction methods. READ MORE

3. 7. Understanding Effects of Isothermal Heat Treatments on Microstructure of LMD-w Titanium Alloy (Ti-6242) : On solution heat treated microstructure

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Noomi Linder; [2020]
   Keywords : Heat Treatments Isothermal Titanium Alloy Ti-6242 Ti6242 Ti-6Al-2Sn-4Zr-2Mo GKN;

   Abstract : The use and knowledge of additive manufacturing technologies are rapidly growing. It is crucial to understand the processing-structure-property relationship, which is highly discussed when trying to understand the science of a material. One commonly used material in aerospace applications is titanium alloy, lately Ti-6Al-2Sn-4Zr-2Mo (Ti-6242). READ MORE

4. 8. Characterization of Heat Treated LMwD Ti-6Al-4V to Study the Effect of Cooling Rate on Microstructure and Mechanical Properties

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Emil Edin; [2019]
   Keywords : Ti-6Al-4V; LMwD; Characterization; Alpha Laths;

   Abstract : In this work, the influence of different cooling rates (5, 20, 50 and 100 °C/s) on the microstructure and mechanical properties of Laser Metal Wire Deposited (LMwD) Ti-6Al-4V was investigated, this was done using a thermal-mechanical physical simulation system (Gleeble 3800, DSI). Two different soak times above β transus (held at 1100 °C), 5 and 40 s, were used and after cooling to 150 °C, the samples were tensile tested. READ MORE

5. 9. An Investigation of Bent-Beam Stress-Corrosion Test for Titanium Alloys

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Daniel León Zapata; [2019]
   Keywords : Hot-salt; Stress-Corrosion Cracking; Titanium Alloy; Hydrogen Embrittlement; Brittle Fracture;

   Abstract : Titanium alloys are highly resistant to all types of corrosion due to their excellent ability to form an oxide film on the surface. However, under certain circumstances, these alloys may experience an environmental degradation which could potentially, under the application of mechanical stress, lead to a complete failure of the material.

6. 10. Microstructural, Mechanical and Tribological Studies of Ti-6Al-4V Thin Plates Produced by EBM Process

   University essay from Högskolan Dalarna/Materialteknik

   Author : Onimisi Calistus Sanni; [2019]
   Keywords : Additive manufacturing AM ; Electron beam melting EBM ; Mechanical properties; Tribological behaviour; Microhardness; Micro tensile; Thin sections; Ti-6Al-4V;

   Abstract : The titanium alloy, Ti-6Al-4V, is vastly studied and used in many applications because it has a transformation microstructure, which can be tailored for apt properties that are consistent up to 500°C. Compared to conventional steels, this alloy favours certain applications due to its high specific strength, hardenability, corrosion resistance, biocompatibility and weldability. READ MORE
