摘要：
Reverted austenite strongly influences the mechanical properties of maraging steels. Therefore, X-ray diffraction using high-energy synchrotron radiation was applied for in-situ studying of the reverse martensitic phase transformation under external load in a PH 13-8 Mo maraging steel. The volume fraction of austenite, the domain size of the crystallites, and the lattice parameters were determined as function of strain for differently aged samples. It is shown that the reverted austenite is not mechanically stable under external load. Scanning of the fractured sample along the axial direction shows that the volume fraction of the austenite and the domain sizes strongly depend on the distance from the point of fracture initiation.
