ENERGY OF ACTIVATION OF THE VT5 AND VT1-0 TITANIUM ALLOYS UNDER SHORT-TERM CREEP IN AIR AND ARGON

DOI: 10.17804/2410-9908.2016.6.100-110

Test results for the short-term creep of commercially pure VT1-0 titanium and the VT5 alloy at temperatures ranging from 673 K to 1323 K and rated tensile stresses ranging between 4.45 and 9.36 MPa in air and argon are presented. The experimental results have shown a considerable decrease in the speed of creep under loading in the argon environment in comparison with that in air. The values of the activation energy determined in tests with a stepwise change of temperature by Dorn’s method have close values for the materials studied in air and argon, 250 to 300 kJ/mol, and this testifies to the identical mechanism of creep.

Keywords: titanium alloys, environmental effect on creep, creep activation energy
