摘要： A three-dimensional multi-shell insulation configured to conform to the shape of a spacecraft component to be insulated. The insulation may have a plurality of nested shell layers that are displaceable relative to each other for providing natural separation between the shell layers when the insulation is used in low-pressure and/or low-gravity space-related applications. To establish the spacing between shell layers, an edge clamp may be operatively coupled to an edge portion on at least one side of each shell layer. The shell layers may have sufficient flexibility and/or may be sufficiently displaceable relative to each other to allow the insulation to be installed or removed from the spacecraft component. One or more restraints may be provided in the space between the shell layers for restricting the relative lateral and/or transverse movement between shell layers for preventing contact. Additive manufacturing may be employed to fabricate the insulation and integrate features.

摘要： Magnesium alloys and a process of manufacturing an article using magnesium alloys. During additive manufacturing, where the magnesium alloy is being deposited in a layer-by-layer manner, solidification of the melted portion of a deposited layer is performed in such a way as to ensure that about 15 percent or more of the portion being solidified includes a non-equilibrium eutectic constituent. This in turn reduces the likelihood of encountering solidification conditions that otherwise would lead to hot tearing problems. Further, upon subsequent heat treatment of the solidified layer, the eutectic constituents that were used for hot tearing resistance are dissolved so that the solidified layer may be returned to a substantially single-phase magnesium matrix such that desirable material properties such as improved flammability point, improved corrosion resistance and one or more of high yield strength, ultimate tensile strength and elongation are promoted.
