  3. 2. Effect of boron and hydrogen on microstructure and mechanical properties of cast Ti-6Al-4V

    Författare :Raghuveer Gaddam; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium alloy; Metallography; Fractography; Castings; Low cycle fatigue; Hydrogen; Boron; Materials science - Construction materials; Teknisk materialvetenskap - Konstruktionsmaterial; Engineering Materials; Materialteknik;

    Sammanfattning : Titanium and its alloys are widely used in applications ranging from aeroengines and offshore equipment to biomedical implants and sporting goods, owing to their high ratio of strength to density, excellent corrosion resistance, and biomedical compatibility. Among the titanium alloys used in aerospace, Ti-6Al-4V (an α+β alloy) is the most widely used, in applications in which the temperature may reach 350°C, at which point it retains good fatigue and fracture properties as well as moderate tensile strength and ductility.
