Mechanical Properties of Titanium Alloys at Operating and Pressure Shaping Temperatures Depending on the Aluminum and Molybdenum Equivalents

Article Preview

Abstract:

The mechanical properties of different classes of titanium alloys have been compared during tensile tests and upset tests in the temperature range of 20-1200 °C. It has been established that at temperatures of 20–500 °C, the maximum strength is observed for the α+β-transition alloys, and at 600–800 °C – for heat-resistant near α-and α+β-alloys. At temperatures exceeding 900 °C and up to the polymorphic transformation point, the softening of titanium alloys is mainly defined by the content of α-stabilizers and neutral hardeners. At temperatures above the polymorphic transformation point, the tensile strength does not depend on the aluminum and molybdenum equivalents.
