However, their application is still limited due to the extremely high brittleness of the Al3Ti phase. In this study, we attempt to address this issue by changing the D022 crystal structure of Al3Ti to the more ductile L12 structure by alloying it with silver. To select the best fabrication regimes of Ti-Ti(Al1-xAgx)3 composites, in situ synchrotron X-ray diffraction analysis was performed to reveal the chemical reactions occurring upon heating the Ti-Al-Ag sample. The analysis showed that the highest amount of Ti(Al1-xAgx)3 phase with the L12 structure appears at 930 °C. This temperature was chosen for subsequent spark plasma sintering experiments. Scanning electron microscopy, energy dispersive X-ray analysis, and X-ray diffraction analysis revealed that the sintered sample consisted mainly of Ti, Ti(Al1-xAgx)3, and a minor fraction of the Ag-Al compound distributed in the central parts of the intermetallic layers and at the grain boundaries. Modification of the titanium trialuminide crystal structure positively affected the properties of the composite, providing a 60\% increase in fracture toughness. The Ag-Al phase also contributed to toughening, causing an additional crack deflection effect.}, language = {en} } @misc{IvanovLazurenkoStarketal., author = {Ivanov, Ivan V. and Lazurenko, Daria V. and Stark, Andreas and Pyczak, Florian and Th{\"o}mmes, Alexander and Bataev, Ivan A.}, title = {Application of Different Diffraction Peak Profile Analysis Methods to Study the Structure Evolution of Cold-Rolled Hexagonal α-Titanium}, series = {Metals and Materials International}, volume = {26}, journal = {Metals and Materials International}, number = {1}, issn = {2005-4149}, doi = {10.1007/s12540-019-00309-z}, pages = {83 -- 93}, language = {en} } @misc{LazurenkoStarkEsikovetal., author = {Lazurenko, Daria V. and Stark, Andreas and Esikov, Maksim A. and Paul, Jonathan and Bataev, Ivan A. and Kashimbetova, Adelya A. and Mali, Vyacheslav I. and Lorenz, Uwe and Pyczak, Florian}, title = {Ceramic-Reinforced γ-TiAl-Based Composites: Synthesis, Structure, and Properties}, series = {Materials}, volume = {12}, journal = {Materials}, number = {4}, issn = {1996-1944}, doi = {10.3390/ma12040629}, pages = {20}, language = {en} } @misc{LazurenkoLaptevGolkovskyetal., author = {Lazurenko, Daria V. and Laptev, Ilia S. and Golkovsky, Mikhail G. and Stark, Andreas and Paul, Jonathan and Bataev, Ivan A. and Ruktuev, Alexey A. and Song, Lin and Gollwitzer, Christian and Pyczak, Florian}, title = {Influence of the Ti/Al/Nb ratio on the structure and properties on intermetallic layers obtained on titanium by non-vacuum electron beam cladding}, series = {Materials Characterization}, volume = {163}, journal = {Materials Characterization}, issn = {1044-5803}, pages = {13}, language = {en} } @misc{LazurenkoBataevMalietal., author = {Lazurenko, Daria V. and Bataev, Ivan A. and Mali, Vyacheslav I. and Jorge, J.
