| Special Titanium Alloys Deposition by Directed Energy Deposition System Jan Dzugan1; Libor Kraus1; 1COMTES FHT INC., Dobrany, Czech Republic; PAPER: 268/Manufacturing/Regular (Oral) SCHEDULED: 15:55/Wed. 30 Nov. 2022/Saitong ABSTRACT: As the additive manufacturing (AM) processes are developing and expanding their capabilities and subsequently also application fields, new alloys are being implemented in order to fulfil specific requirements for highly demanding applications. In the current paper, beta-titanium alloy Ti-13Zr13Nb is investigated. This materials is special due to low elastic modulus and its certification for bio applications. The experimental material is deposited by powder blown directed energy deposition process. Microstructure and local mechanical properties at room temperature under quasi-static loading conditions are investigated here. Optical and electron microscopy investigations including EBSD analyses are carried out here in order to provide detailed information on the microstructure of the AM deposited material. Mechanical properties in terms of tensile properties are investigated using miniaturized tensile test specimens excised in various orientations regarding the deposition process. Microstructure and mechanical properties homogeneity together with imperfections observations are investigated for the material of interest. Obtained results are compared with properties of the other Ti-alloys produced in conventional way and by AM processes. |
