titanium gr5 alloy mateiral's characteristic

titaniumcn GR5 titanium alloy heat treatment: mpa, solid solution strengthening TC4 material after processing, the strength increase is not big, also to 1100 mpa, strength is in commonly 900 mpa annealing condition
GR5 thermal expansion coefficient:
GR5 titanium alloy has excellent corrosion resistance, small density, high specific strength and good toughness and weldability and a series of advantages, in the aerospace, petrochemical industry, shipbuilding, automobile, medical departments have been successful applications.
GR5 titanium alloy mechanical properties:
Sigma b / 895 MPa or greater tensile strength, of specified residual elongation stress in the sigma r0.2 / MPa or greater 825, 5 (%) of 10 or higher elongation delta, reduction of area bits (%) of 25 or higher
GR5 titanium alloy density:
(4.5 g/cm3) working temperature - 100 ~ 550 ℃)
GR5 titanium alloy chemical composition:
Allowance GR5 titanium (Ti), iron (Fe) 0.30, or less carbon (C) 0.10, or less nitrogen (N) 0.05 or less, hydrogen (H), 0.015 or less oxygen (O) of 0.20 or less, aluminum (Al) 5.5 ~ 6.8, vanadium (V) 3.5 ~ 4.5

GR5 belong to heat treatment to strengthen titanium alloy, it has good weldability sheet formability and forging performance.Used in the manufacture of jet engine compressor blade, impeller, etc.Such as the gear wheel and other parts, fasteners, stents, aircraft accessories, frame, purlin, pipeline structure, application is very broad.

When GR5 titanium alloy casting, casting and mold GR5 titanium alloy castings is interfacial reaction between the root cause of occurrence quality problem.In addition, similar to cast steel, cast iron and aluminum alloy castings, casting gr5 titanium alloy will happen many common casting defects, these defects including porosity, shrinkage cavity, shrinkage), inclusions, cracks, adhering sand, burr, coolsun (stray), running fire, misrun and partial core surface and internal quality problems.These defects are directly related to the chemical and physical properties of cast titanium alloy, but also affected by the vacuum melting and casting method characteristics.
