Experimental Study of the Anisotropic Behavior of the CMSX2 Single-Crystal Superalloy Under Tension-Torsion Loadings

Source

A thin tube made in single crystal is submitted to tension-torsion loading. The axis of the tube coincides with the 〈001〉 material axis. Local strain measurements made by means of strain gages experimentally demonstrate that the deformation is mainly localized in the 〈110〉 type zones. This is confirmed by microstructural observations of replicas. An experimental loading surface in these soft zones is derived. An analysis of the experimental data is successfully made through the Schmid law, involving both cube and octahedral slip.
