Factors affecting the constitution and stability of iron-base austenitic alloys.
A study of the constitution of Fe-Cr-Ni based alloys has been carried out. The isothermal sections of the ternary Fe-Cr-Ni system have been determined for temperatures between 1150 C and 650°C by analysing the composition of the individual phases by a micro-probe technique. The transformation …

Development of the Strain-To-Fracture Test to Study Ductility-Dip Cracking in Austenitic Alloys
… of factors thataffect cracking.Three austenitic alloys were tested using the strain-to-fracture test: Type 310 stainless steel, Ni-base Alloy 690, and AL-6XN. Alloy 690 was found to be the most susceptible to DDC with a low threshold strain and wide DTR. Type 310 stainless steel …

The SCC behavior of austenitic alloys in an oxygen-free CO₂ environment containing chloride ions
Stress-corrosion cracking of austenitic alloys in an oxygen-free carbon dioxide environment containing chloride ions was studied under static conditions. Stiffness and X-ray measurements supported results obtained from SEM photomicrographs indicating that the CT specimens loaded to a stress …

Spin cluster expansion approach to the interplay between short-range order and interstitial atoms in austenitic stainless steels
… severely degrades the mechanical properties of austenitic stainless steels, thus limiting their use in hydrogen transport and storage applications. Despite extensive investigations, the dominant underlying mechanism of HE remains unclear. Recent studies have highlighted short-range order (SRO) …

Radiation-induced microstructural and mechanical property modifications in advanced alloys
… Upon irradiation, the atoms in metals and alloys undergo successive displacements and point defects are created far exceeding the equilibrium concentrations. The material system is driven into thermodynamic nonequilibrium and the microstructure can be modified in many ways: dislocation …
