Special Issue Information

Dear Colleagues,

In recent years, the demand for advanced alloys has been steadily increasing across various industries, driven by the need for materials that can meet the high requirements of modern applications. The aerospace, automotive, electronic, building, sport and medicine sectors, among others, are continually seeking alloys with superior performance characteristics to enhance their specific strength; corrosion, fatigue, creep and wear resistance; and thermal stability, formability, machinability, and weldability, as well as their cost effectiveness and environmental and health safety. New light alloys are able to meet these requirements, and as industries continue to evolve and new technological challenges arise, the development of high-performance light metal alloys has become increasingly important.

For this Special Issue, we welcome submissions on investigations focused on novel light metal alloys and composites with properties superior to those currently in use, including those used as coatings as well as those containing light elements like scandium, lithium, yttrium or alkaline earth metals to improve the properties and reduce the weight of products.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Innovations in alloy composition;
  • New methods for alloy production and processing;
  • Characterization of microstructures using modern techniques, as well as microstructural modelling and simulations;
  • Relationships between microstructure and properties of light metal alloys;
  • Innovative or potential applications;
  • Environmental impact and recycling.

We highly encourage you to share your research findings and insights with the scientific community through this Special Issue.

We look forward to receiving your contributions.

This study investigates the characteristics of the Ti-5Al-2.5Sn-0.2C alloy, an alpha titanium alloy containing approximately 0.2 wt% carbon—a concentration significantly exceeding the standard allowable limit of 0.08 wt%. The Ti-5Al-2.5Sn-0.2C alloy was melted in a vacuum induction furnace with a cold copper crucible, processed into bar form through hot rolling, and subsequently annealed under standard conditions. The microstructure and mechanical properties of the Ti-5Al-2.5Sn-0.2C alloy were systematically compared with those of the Ti-5Al-2.5Sn alloy (Grade 6), which possesses a similar chemical composition. The results revealed that the addition of 0.2 wt% carbon significantly influences the alloy’s solidification process, phase transformation temperatures, phase composition, and phase lattice parameters. Moreover, the carbon addition enhances key mechanical properties, including tensile strength, yield strength, hardness, and wear resistance, as well as creep and oxidation resistance. While a slight reduction in plasticity and increase in impact energy were observed, the alloy remained within the permissible range defined by existing standards. Full article
