Prof. Hongbiao Dong (University of Leicester)23/11/2018, 11:00New MaterialsOral PresentationNiobium silicide-based alloys, in the application of gas turbine blades, promise significant efficiency improvements compared to current Ni-based alloys. The higher temperature capability would allow the engine to run at a higher temperature than that of current alloys, increasing engine efficiency. Nb-Si based composites possess a lower density, due to the presence of ceramic phases such as...Go to contribution page

Mr Rudolf Gradinger (LKR Leichtmetallkompetenzzentrum Ranshofen GmbH)23/11/2018, 11:20New MaterialsOral PresentationAn increasing availability of capable additive manufacturing processing technologies is in parallel needing high-performance metallic materials in order to create efficient, light weight design parts. The consortium of the M-Era.net project HiPA²l has set goals to develop innovative Aluminium alloys designed for usage in wire-based arc welding AM processes. The alloying and processing...Go to contribution page

Mr Philip Emmerling (FIT AG)23/11/2018, 11:40New MaterialsOral PresentationOne remaining technical restriction in additive manufacturing to-date is size which is defined by the size of the build space. To overcome this restriction, FIT has introduced the new WAAM technology (Wire Arc Additive Manufacturing) for big metal parts. The resulting massive raw parts are to be finished by CNC milling. It is also possible to work on a pre-fabricated corpus. The WAAM build...Go to contribution page

Dr Eva Maria Pérez-Soriano (University of Seville)23/11/2018, 12:00New MaterialsOral PresentationToday Ti6Al4V alloy, also known as Titanium Grade 5, is in use worldwide. However, several authors studied the difficulty of its machining due to their low thermal conductivity, high chemical reactivity at high temperatures or low modulus of elasticity, which can lead to damage vibrations in the specimen. In view of the above, a manufacturing technology is developed, and it is revolutionizing...Go to contribution page
