“…For example, a compositionally graded specimen was used to evaluate the mechanical properties such as radiation damages and irradiation-assisted stress corrosion cracking of AM materials [51]. An AM 316LN austenitic stainless steel with high-density solidification cells was irradiated using 3.5 MeV Fe ion to a peak dose of 220 dpa at 450 °C [52]. The irradiation damage and the irradiationassisted stress corrosion cracking behavior of both proton-irradiated AM and wrought 316L stainless steel were examined with about 4% plastic strain [53].…”

This review paper provides insights the into current developments in additive manufacturing (AM) techniques. The comprehensive presentations about AM methods, material properties (i.e., irradiation damage, as-built defects, residual stresses and fatigue fracture), experiments, numerical simulations and standards are discussed as well as their advantages and shortages for the application in the field of nuclear reactor. Meanwhile, some recommendations that need to be focused on are presented to advance the development and application of AM techniques in nuclear reactors. The knowledge included in this paper can serve as a baseline to tailor the limitations, utilize the superiorities and promote the wide feasibilities of the AM techniques for wide application in the field of nuclear reactors.

“…Moreover, historically accumulated knowledge built on conventional alloy manufacturing, together with recent advances in additive manufacturing, is facilitating breakthroughs, especially in the development of alloys depending sensitively on both chemical disorder and intricately designed microstructures for certain targeted functionalities. Additive manufacturing routes may overcome conventional manufacturing limits by eliminating post-thermomechanical processing and may produce inimitable heterogeneous precipitates, grain structure and morphology, or subgrain solidification cells, as recently demonstrated in additive manufacturing stainless steels. − Synergistic effects from valence electrons (i.e., alloying TMs with larger differences in the outermost electron counts); atomic-level disorder (i.e., differences in atomic volume and mass); and inhomogeneity from the nanoscale to the micro-, meso-, and macroscales in complex alloys composed of TMs are key factors to be modified to achieve desirable properties in structural alloys.…”

Tunable Chemical Disorder in Concentrated Alloys: Defect Physics and Radiation Performance

The development of advanced structural alloys with performance meeting the requirements of extreme environments in nuclear reactors has been long pursued. In the long history of alloy development, the search for metallic alloys with improved radiation tolerance or increased structural strength has relied on either incorporating alloying elements at low concentrations to synthesize so-called dilute alloys or incorporating nanoscale features to mitigate defects. In contrast to traditional approaches, recent success in synthesizing multicomponent concentrated solid-solution alloys (CSAs), including mediumentropy and high-entropy alloys, has vastly expanded the compositional space for new alloy discovery. Their wide variety of elemental diversity enables tunable chemical disorder and sets CSAs apart from traditional dilute alloys. The tunable electronic structure critically lowers the effectiveness of energy dissipation via the electronic subsystem. The tunable chemical complexity also modifies the scattering mechanisms in the atomic subsystem that control energy transport through phonons. The level of chemical disorder depends substantively on the specific alloying elements, rather than the number of alloying elements, as the disorder does not monotonically increase with a higher number of alloying elements. To go beyond our knowledge based on conventional alloys and take advantage of property enhancement by tuning chemical disorder, this review highlights synergistic effects involving valence electrons and atomic-level and nanoscale inhomogeneity in CSAs composed of multiple transition metals. Understanding of the energy dissipation pathways, deformation tolerance, and structural stability of CSAs can proceed by exploiting the equilibrium and non-equilibrium defect processes at the electronic and atomic levels, with or without microstructural inhomogeneities at multiple length scales. Knowledge of tunable chemical disorder in CSAs may advance the understanding of the substantial modifications in element-specific alloy properties that effectively mitigate radiation damage and control a material's response in extreme environments, as well as overcome strength−ductility trade-offs and provide overarching design strategies for structural alloys.

“…Thus, they are widely used in modern industries (medical devices, power plants, steamships, and hightemperature bolts). They are also widely used as structural materials in nuclear reactors due to their superior properties [14,15]. In addition, austenitic stainless steels are commonly preferred in the food and biomedical fields due to their excellent biocompatibility compared to other non-austenitic stainless steels [16][17][18][19][20][21][22][23].…”

In this study, 316L stainless steel (SS) samples produced with standard parameters using the Additive Manufacturing method were heat treated with different parameters, and the effects of heat treatment on the microstructure, phase changes, hardness, porosity, and corrosion of the material were examined in detail. The results showed that the as-built microstructure of 316L stainless steel material produced by Additive Manufacturing deteriorated as the heat treatment temperature increased and the hardness decreased. The corrosion resistance of the material increased. The best corrosion resistance was obtained from heat treatment at 1150°C for 2 h.
