Ti-17
Ti 17 is an alloy developed by General Electric for high-strength, deep-hardness applications such as fan and compressor discs and other large components. It is a beta-phase-rich alpha-beta alloy. It has higher creep resistance and tensile strength than Ti6Al4V. Ti 17 also has lower density and higher modulus compared to other titanium alloys. This alloy is produced using the PAM (plasma cold hearth melting) method followed by VAR (vacuum arc remelting).
