Advancement of Compositional and Microstructural Design of Intermetallic γ-TiAl Based Alloys Determined by Atom Probe Tomography
Advanced intermetallic alloys based on the γ-TiAl phase have become widely regarded as most promising candidates to replace heavier Ni-base superalloys as materials for high-temperature structural components, due to their facilitating properties of high creep and oxidation resistance in combination with a low density. Particularly, recently developed alloying concepts based on a β-solidificatio...

متن کاملSynthesis of Nano - Crystalline Γ - Tial Materials
One of the principal problems with nano-crystalline materials is producing them in quantities and sizes large enough for valid mechanical property evaluation. The purpose of this study was to explore an innovative method for producing nano-crystalline γ-TiAl bulk materials using high energy ball milling and brief secondary processes. Nano-crystalline powder feedstock was produced using a Fritsc...
متن کاملATOMISTIC STUDIES OF JOGGED SCREW DISLOCATIONS IN y-TIAL ALLOYS
The behavior of jogged screw dislocations in y-TiAl alloys has been investigated with large-scale molecular dynamics (MD) simuIations. We find a new mechanism for formation of pinning points in jogged screw dislocations. We also find that the critical height for the jogs in the +[i10] directions on the (001) plane to move nonconservatively is between 3ro and 4r0, where ro is the nearest neighbo...
متن کاملOptimizaton of Mo-Si-B Intermetallic Alloys
Mo-Si-B intermetallics consisting of the phases Mo3Si and Mo5SiB2, and a molybdenum solid solution (“ -Mo”), have melting points on the order of 2000 °C. These alloys have potential as oxidationresistant ultra-high-temperature structural materials. They can be designed with microstructures containing either individual -Mo particles or a continuous -Mo phase. A compilation of existing data shows...
