Available in PDF, EPUB and Kindle. Book excerpt: Among the various mechanisms and processes by which energetic irradiation can alter the phase stability of alloys, radiation-induced segregation is one of the most important phenomena. Radiation-induced segregation in alloys occurs as a consequence of preferential coupling between persistent fluxes of excess defects and solute atoms, leading to local enrichment or depletion of alloying elements. Thus, this phenomenon tends to drive alloy systems away from thermodynamic equilibrium, on a local scale. During charged-particle irradiations, the spatial nonuniformity in the defect production gives rise to a combination of persistent defect fluxes, near the irradiated surface and in the peak-damage region. This defect-flux combination can modify the alloy composition in a complex fashion, i.e., it can destabilize pre-existing phases, causing spatially- and temporally-dependent precipitation of new metastable phases. The effects of radiation-induced segregation on local phase transformations in Ni-based alloys during proton bombardment and high-voltage electron-microscope irradiation at elevated temperatures are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The microstructures of a simple ternary Fe-16Cr-15Mn alloy and a solute modified Fe-12Cr-18Mn-0.26C WVN alloy were examined after irradiation with 4-MeV Ni ions (single-beam irradiation) and with 4-MeV Ni ions with simultaneous injection of energy-degraded 1-MeV He ions (dual-beam irradiation). The microstructure prior to irradiation revealed that the ferrite phase was dominant in the Fe-16Cr-15Mn alloy in spite of the prediction of the Schaef-fler diagram, while the Fe-12Cr-18Mn-0.26C WVN alloy contained only austenite. In the irradiated Fe-16Cr-15Mn alloy, formation of a lenticular-shaped phase was observed following irradiation to 15 dpa or more. Electron diffraction analysis demonstrated that this was an austenite phase. Austenite formation was observed in both dual-beam and single-beam irradiations. The fraction of this phase increased abruptly in the early stages of irradiation. The volume fraction saturated to about 70% following irradiation beyond 20 dpa, but the saturation appeared to occur faster in dual-beam irradiations than in single-beam irradiations. Cavities were formed uniformly only within the austenite phase. Local swelling reached as high as 50% following irradiation at 773 K to 120 dpa. In the Fe-12Cr-18Mn-0.26C WVN alloy, the austenite structure was stable during irradiation, and no radiation-induced phase transformation was observed. Cavity formation was strongly suppressed in this alloy. Small cavities with a number density less than 1022 m-3 were observed following irradiation at 773 K to 35 dpa. The calculated swelling from these cavities was estimated as high as 0.4%, which was much lower than the swelling level in dual-beam irradiated 316 stainless steel.
