Coupling multi-scale mechanical testing techniques reveals the existence of a trans-granular channel fracture deformation mechanism in high dose Inconel X-750

Recent testing has shown that Inconel® X-750 materials have lost strength and ductility following irradiation, which may raise concerns over the structural integrity of the material. Bulk component compression testing shows irradiation temperature has a clear influence on mechanical behaviour; mater...
