Summary
Combined tension-torsion creep tests of directionally solidified IN738LC at 850°C are first discussed to find features which become noticeable with the advance of creep deformation. Analysis based on the crystallographic slip theory of finite deformation then shows that crystalline lattice rotation explains the experimental features; it is mostly responsible for the change of the noncoaxiality between creep rate and stress in combined tension-torsion creep, and partly for the earlier appearance of tertiary creep under combined tension-torsion than under pure tension and torsion.
