摘要： An alloy part is cast in a mold (280) having a part forming cavity (292, 294, 296). The method comprises pouring a first alloy into the mold. The pouring causes: a surface (550) of the first alloy in the part forming cavity to raise relative to the part forming cavity; a branch flow of the poured first alloy to pass upwardly through a first portion (304) of a passageway; and the branch flow to pass downwardly through a second portion (310), of the passageway; solidifying some of the first alloy in the passageway to block the passageway while at least some of the first alloy in the part forming cavity remains molten. A second alloy is poured into the mold atop the first alloy and solidified.
摘要翻译：将合金部件铸造在具有部件形成空腔（292,294,296）的模具（280）中。该方法包括将第一合金浇注到模具中。倾倒导致：部件形成腔中的第一合金的表面（550）相对于部件形成腔升高; 所浇注的第一合金的分支流向上穿过通道的第一部分（304）; 并且分支流向下通过通道的第二部分（310）; 固化通道中的一些第一合金以阻塞通道，同时部件形成空腔中的至少一些第一合金保持熔化。将第二种合金倒入第一种合金顶部的模具中并固化。

摘要： A high temperature nanocellular foam seal material has pores, interconnecting ligaments, and nodes where three or more ligaments intersect. The ligament cross-section thickness is less than 200 microns and the distance between nodes is less than 1000 microns. The material's high compliance and elastic springback can be tailored to an application by varying the foam architecture. Metal, intermetallic, and ceramic nanocellular foams can be used as seal materials in the hot gas path of a turbine engine.
