Creep behavior of Ti-600 alloy solutioned at β and α+β region

摘要：

　　Creep tests were carded out on one kind of near alpha titanium alloy named after Ti-600 at 550 ℃,600 ℃ and 650 ℃ with the same stress of 300 MPa.The calculated activation energies for the alloy solutioned atβand α+ β region are 490.1 kJ/mol and 473.5 kJ/mol,respectively.Transformed βgrains become coarsened and twisted,and the short primary α groins grow up,α plus β lamellar in transformed β grains elongate apparently after creep tests.
