    摘要： Articles (200) suitable for use as high-temperature machine components include a substrate (202) and an environmental barrier coating (210) disposed over the substrate (202), where the environmental barrier coating (210) includes at least one hermetic self-sealing layer (212) formed from a mixture including an alkaline earth metal aluminosilicate and a rare-earth silicate, and where the at least one hermetic self-sealing layer (212) exhibits substantially no net remnant or residual expansion when subjected to high temperature heat treatment. The environmental barrier coating (210) can further include a bondcoat (204) disposed between the substrate (202) and the hermetic self-sealing layer (212), a topcoat (214) disposed over the hermetic self-sealing layer (212), and/or an intermediate layer (216) disposed between the hermetic self-sealing layer (212) and the bondcoat (204). The intermediate layer (216) can include a barrier material that is substantially inert with respect to silica.

    摘要： A material and an article comprising the material are disclosed. The material comprises a plurality of structural components (100). The structural components (100) are configured in a series of increasing structural component size classes. The series has a base unit size class (102) and at least one modular size class (104), and a component of the at least one modular size class (104) comprises a plurality of components of the next smaller size class in the series. The structural components of the base unit size class (102) comprise at least one bulk phase (103), and the structural components (100) are bonded together at interfaces (112). Mechanical damage originating within a modular size class structural component (104) is energetically favored to propagate in a distributed fashion among the plurality of structural components contained within the modular size class structural component (104).
