Abstract: A fracture stage is designed to permit slow strain‐rate tensile fracture of metallic samples inside the Auger vacuum chamber. The fracture stage consists of two crossheads, one fixed and one moveable. A small electric motor drives the moveable crosshead to separate from the fixed crosshead at a constant rate down to 7×10−4 cm/s. Samples remain attached to the sample carousel stage during loading and following fracture, they can be quickly translated and rotated into alignment with the Auger analyzer. Tests on hydrogen charged Inconel 600 result in fracture times of 2–3 min and fracture strains of 4%–6% yielding a fracture surface that is in excess of 75% intergranular. This technique is recommended for grain boundary analysis of ductile austenitic alloys.
