A special issue of Metals (ISSN 2075-4701).
Deadline for manuscript submissions: 31 October 2020.
Interests: titanium alloys; hot deformation; superplasticity; ultrafine-grained materials, superalloys, directional solidification
Titanium alloys, thanks to unique physical and chemical properties (mainly high relative strength combined with very good corrosion resistance), are considered as advanced metallic materials. Their development has led to design of several groups of structural alloys, including single-phase: α or β alloys, two-phase α + β alloys—the most popular ones—and TiAl intermetallic alloys. The main application areas of titanium alloys include transportation (mainly aerospace structures), machine building, fuel-energetic industry and medicine. The application of conventional titanium alloys is limited due to their high chemical affinity to atmospheric gases (single α phase alloys can be used up to 600 °C). However, Ti-based intermetallic alloys seems to be promising alternative materials for high temperature use. Obviously, it needs to overcome some technological problems—like low ductility—which have been partially resolved over the last decades. Another important feature of titanium is its remarkable biocompatibility. Especially low Young’s modulus titanium alloys are considered nowadays as valuable biomaterials used for bone implants (including “gum metals”). Titanium alloys are also good materials for metal matrix composites (MMC’s). Their main attractions are high strength and stiffness—dependently on the type of reinforcement.
The range of material applications are also related to modern manufacturing and processing technologies. In case of titanium and its alloys, interesting results were obtained by grain refinement, which causes high strength increase. Pure nanocrystalline titanium is characterized be the strength level very close to solution-strengthened titanium alloys. Moreover, ultrafine-grained titanium alloys exhibit high superplastic deformability. Another developing processing areas worth mentioning are: surface engineering, joining methods (e.g. diffusion bonding or friction stir welding—FSW) and highly promising additive manufacturing (AM) method.
The purpose of this Special Issue is to collect works related to various aspects of research on titanium alloys and Ti-based matrix composites—manufacturing and processing methods and materials characterization. It is my pleasure to invite you to submit manuscripts for this Special Issue. Full papers, communications, and reviews are all welcome.
