摘要：

Reaction products at the boundary between Si3N4 and Ag‐Cu‐Ti braze alloy have been characterized by transmission electron microscopy. Beyond the TiN adjoining the Si3N4 substrate is a continuous layer of a previously unreported, orthorhombic Ti‐Si‐Cu‐N compound. Evidence of additional cubic and hexagonal Ti‐Si‐Cu‐N phases is also found; these exist as isolated grains farther from the substrate. The cubic compound is probably an η‐type M6X phase of the sort observed at other ceramic‐metal interfaces. These “dilute ceramics,” in which metallic constituents dominate, are common transitional phases in ceramic‐metal systems. Copyright © 1990, Wiley Blackwell. All rights reserved
