The effect of neutron irradiation in a helium atmosphere on the mechanical properties of 18Cr10NiTi austenitic steel

This paper reports neutron irradiation induced effects on 08Cr18Ni10Ti austenitic steel, which is one of the structural materials of the IVG.1M research reactor. Chosen samples were stored in the beryllium displacer at two different elevation heights and the radiation dose with fast fluence of 0.4·1019 n/cm2 and 4.3·1019 n/cm2. Thorough material analysis reports changes in hardness values, plasticity and microstructure

The Impact

AbstractThe effect of aging heat treatment on the microstructure and mechanical properties of 10Cr20Ni25Mo1.5NbN austenitic steel was investigated in this article. The microstructure was characterized by scanning electron microscopy, energy dispersive spectrometry and transmission electron microscopy. Results show that the microstructure of 10Cr20Ni25Mo1.5NbN austenitic is composed of austenite. This steel was strengthened by precipitates of secondary phases that were mainly M23C6 carbides and NbCrN nitrides. As aging treatment time increased, the tensile strength first rose (0–3,000 h) and then fell (3,000–5,000 h) due to the decrease of high density of dislocations. The impact absorbed energy decreased sharply, causing the sulfides to precipitate at the grain boundary. Therefore, the content of sulfur should be strictly controlled in the steelmaking process.
