Mechanical Behavior of Metallic Materials

Dear Colleagues,

The mechanical properties of metallic materials determine their suitability for a variety of load-bearing or structural applications, such as rebars in the construction industry, turbine blades in the aerospace industry, hip implants in the biomedical industry, and fuel cladding materials in the nuclear industry. The strength, ductility, toughness, and stiffness at room temperature of these materials, as well as their formation conditions—whether under high temperatures or cryogenic temperatures, and under monotonic or cyclic loading conditions—are important properties that must be evaluated before a material is selected for a particular application.

Testing techniques for the evaluation of material properties at various scales, including creep, nanoindentation, fatigue, and strain rate, are well developed. However, the field of materials engineering is very dynamic, and the community is continuously striving to develop materials with better peformance, greater durability, and lower costs.

Additive manufacturing has kindled substantial interest in the mechanical properties of additively manufactured materials. Connections have been established between the mechanical properties and microstructure of additive manufactured materials. Similarly, the field of high-entropy alloys and complex concentrated alloys has provided avenues for systematic investigations into their mechanical properties. On the superalloys front, substantial attention is paid to studying the high-temperature mechanical behavior of new-generation superalloys, such as cobalt-based superalloys. Equally, there is extensive interest in evaluating the mechanical behavior of coatings deposited using the latest techniques, such as cold spraying and laser processing. Hence, it is necessary to periodically review and document the developments that are taking place in the field of materials engineering by studying the mechanical properties of new-generation materials using existing or new techniques.

In this Special Issue, we welcome original research articles and reviews on the topic of the mechanical behavior of metallic materials. Research areas may include (but are not limited to) the mechanical behavior of materials for aerospace, biomedical, nuclear, oil and gas, and construction applications. We will be accepting articles on the mechanical behavior of materials produced in both bulk and small volumes, including coatings, as well as on the effects of the environment (radiation and corrosion). In situ testing of the mechanical behavior of metallic materials using SEM, TEM, etc., is also of interest.

Investigations may report evaluations of the mechanical behavior of these materials using different modes of testing, including tension, compression, bending, torsion, and indentation. Creep, fatigue, and creep–fatigue interactions will also be considered in this Special Issue.

Investigations may be focused on (but not limited to) steels, titanium-based alloys, titanium aluminides, zirconium alloys, high-entropy alloys, and superalloys, viz. nickel-based, cobalt-based, as well as solder materials used in electronic packaging. Studies on the mechanical behavior of metal matrix composites of the abovementioned alloys with ceramic reinforcements will also be considered for publication in this Special Issue.
