Prediction of mechanical properties of Ti-6Al-4V forgings based on simulation of microstructure evolution
(2020)Procedia Manufacturing ~ 23rd International Conference on Material FormingTitanium alloys are widely used in the aerospace industry as a structural material. Since this application is critical, the titanium alloys must have high mechanical properties both at room and at elevated temperatures. The thermomechanical processing of titanium alloys during forging determines the microstructure of the manufactured parts to a large extend. The final mechanical properties are attained by the subsequent heat treatment. ...Conference Paper -
Hot workability of a spark plasma sintered intermetallic iron aluminide alloy above and below the order-disorder transition temperature
(2020)Procedia Manufacturing ~ 23rd International Conference on Material FormingThe Fe-25Al-1.5Ta alloy has proved to be qualified for structural applications at and above 600°C due to a superior creep resistance to its binary counterpart. The creep resistance of the Fe-25Al-1.5Ta alloy at 650°C surpasses that of the P92 martensitic-ferritic steel, which is one of the most developed creep resistant alloys for steam turbine applications. From the viewpoint of cost-effectiveness in real-scale forgings, it is important ...Conference Paper -
New hybrid manufacturing routes combining forging and additive manufacturing to efficiently produce high performance components from Ti-6Al-4V
(2020)Procedia Manufacturing ~ 23rd International Conference on Material FormingHigh-performance components from titanium alloy Ti-6Al-4V are used in many industries, particularly in aerospace, but also in the automotive and medical market. Traditionally, such components are produced by hot forging and subsequent post processing. The multi-stage forging process requires several expensive dies and leads to components with a high material oversize. Therefore, costly machining operations with machining removal up to ...Conference Paper -
Laser metal deposition of Ti-6Al-4V with a direct diode laser set-up and coaxial material feed
(2020)Procedia Manufacturing ~ 23rd International Conference on Material FormingThe production of components from the titanium alloy Ti-6Al-4V is of great importance for many industrial fields, especially for the aerospace industry. Laser metal deposition (LMD) processes can be used either for manufacturing of components or repair. The majority of LMD set-ups use a concentrical laser and a powder feed through nozzles focusing the powder on a spot. Gas shielding is problematic in such set-ups, which hence require the ...Conference Paper
