Abstract
An investigation of thermomechanical testing and deformation behavior of tubular specimens under torsional loading is described. Experimental issues concerning test accuracy and control specific to thermomechanical loadings under a torsional regime are discussed. A series of shear strain-controlled tests involving the nickel-base superalloy Hastelloy X were performed with various temperature excursions and compared to similar thermomechanical uniaxial tests. The concept and use of second invariants of the deviatoric stress and strain tensors as a means of comparing uniaxial and torsional deformations is presented and critiqued for its applicability to the present data. The hardening behavior of the torsional specimens is also briefly presented and discussed in light of previous thermomechanical tests conducted under uniaxial conditions.
