What are additive manufactured stainless steels for hydrogen applications?3 answersAdditive manufactured stainless steels for hydrogen applications are a novel approach to fabricate complex nuclear components. These steels are produced using techniques such as selective laser melting (SLM) and laser powder-bed fusion (LPBF). They offer advantages such as the ability to create complex geometries and excellent mechanical properties comparable to or exceeding that of conventional austenitic stainless steels. However, the microstructures of these steels differ from conventionally processed materials, with features such as increased ferrite content and dislocation densities, as well as chemical inhomogeneity. These microstructural differences can affect hydrogen transport and trapping in the materials. Studies have shown that hydrogen permeability remains relatively unchanged in additive manufactured stainless steels, but they exhibit greater hydrogen isotope trapping compared to conventional steels. The presence of delta ferrite and chemical inhomogeneity can lead to severe hydrogen-assisted failure in conventionally processed materials, while additive manufactured steels with a fully austenitic structure and homogeneous elemental distribution show enhanced strength without promoting harmful hydrogen embrittlement effects.

The type of grain boundary can indeed affect the 1D profile in atom probe tomography (APT). Grain boundaries are two-dimensional crystal defects where lattice discontinuity and/or chemical inhomogeneity exist. By tailoring the structures of grain boundaries, desired bulk properties can be obtained. Special grain boundaries with low-Σ CSL have distinct properties such as lower energies and lower tendencies to trap impurities and solutes. Additionally, grain boundaries can exhibit different chemical states, resulting in significant differences in properties such as mobility and segregation coefficients. Compositional modifications can be used to manipulate the properties of grain boundaries, leading to the concept of grain boundary segregation engineering. Therefore, the type of grain boundary can have a significant impact on the 1D profile in APT due to the variations in properties and behaviors of different grain boundaries.What are the microstructural features that are associated with high cycle fatigue in Ti-64?

The microstructural features associated with high cycle fatigue in Ti-64 alloys include the presence of α colonies or basketweave microstructures. β-annealed Ti-64 alloys with a microstructure of α colonies exhibit slightly inferior resistance to high cycle fatigue compared to those with a microstructure of basketweave. In addition, the fatigue crack propagation rates are lower in β-annealed Ti-64 alloys with a microstructure of α colonies, particularly in the low ΔK regime. Crystallographic crack growth is observed in the microstructure of α colonies, resulting in cleavage facets on the fracture surface and less fatigue damage at the crack tip. The presence of nanograins and deformation twins in some α grains at or near crack surfaces is also observed in Ti-64 alloys. These microstructural features play a role in the fatigue behavior and failure mechanisms of Ti-64 alloys.How can single crystal blades be manufactured?

Additionally, a ceramic mold shell can be used for casting single crystal blades, where the hollow area of the shell is filled with a heat insulation material to reduce heat loss and improve the temperature gradient during casting. Furthermore, a single crystal manufacturing device that uses the Czochralski method can be employed, which includes a main chamber, a drawing chamber, a cooling cylinder, and a cooling assistance cylinder to efficiently cool and grow the single crystal.
