Recently, the development of materials for the automotive, aerospace, and medical industries has garnered significant interest among researchers. Materials such as cast iron, nickel-based alloys, steels, and other metals with impressive mechanical properties have traditionally been utilized in manufacturing within these sectors. However, titanium and its alloys have emerged as outstanding candidates due to their superior characteristics. Titanium and its alloys are strongly associated with aerospace applications. They offer an exceptional strength-to-weight ratio, with a density of about 4.5 g/cm³, making them approximately half as heavy as steel or nickel-based superalloys. Additionally, they exhibit excellent corrosion resistance. This paper provides a brief overview of titanium alloys, focusing on their aerospace applications, exemplified by their use in the airframe and engine components of Russian aircraft. The most critical properties considered were thermal and mechanical performance.
