Creep in Beta-Alloy of Titanium IVT-1,
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
Pagination or Media Count:
In creep testing alloy IVT-1 it was discovered that if two specimens tested under identical conditions show different initial deformations, then, as a rule, the specimen with the greater initial deformation has lower creep than the specimen with the lower initial deformation. At test temperatures of 100-250C and loads of 120-75 kgsq mm there was little increase in total deformation of the alloy specimens with an increase in time under the load. Thus, at the greatest applied stress of 120 kgsq mm and a temperature of 100C there was a maximal increase in total deformation of 0.04. The structure of the alloys was studied after creep testing at the test temperatures and stresses. Author
