Abstract

Harvey HA-7146 is an alpha-beta type titanium-base bar and forging alloy developed to combine high temperature strength and stability with good forgability. It is recommended for aircraft gas turbine engine components due to its improved stress stability and creep resistance. It responds to an age hardening heat treatment. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Ti-39. Producer or source: Harvey Aluminum Company.
