Reactive Synthesis of Ceramic‐Metal Composites

Advanced Engineering Materials, 2018
Since the last century, a variety of reactive synthesis methods has been extensively studied and developed to derive ceramic composite materials, which show superior mechanical and physical properties for numerous applications. Melt casting/infiltration is one of the preferred techniques to fabricate ceramic‐metal composites. In this article, different

Microwave Sintering of Metal-Ceramic and Ceramic-Ceramic Composites

MRS Proceedings, 1994
ABSTRACTPolyphase ceramic and metal ceramic composites with at least one high dielectric loss component are potential candidates for application of microwave sintering, because of the high effectiveness of power dissipation and short sintering times.

Biomimetic Processing of Ceramics and Ceramic-Metal Composites

MRS Proceedings, 1990
ABSTRACTBiomimetic design and processing of laminated B4C-Al cermets, based on knowledge gained from the microstructure-property characterization of abalone shells, is described. In the nacre section of the shell, the microstructure is highly organized as CaCO3(aragonite) crystals, with a thickness of 0.25 μm, separated by a layer of organic matter 300–

Structure and Composition of Metal/Ceramic Interfaces

Key Engineering Materials, 1995
Abstract The structure and composition of metal/ceramic interfaces play an important role for the properties of composites, for the bonding of bulk metals (or metallic alloys) to bulk ceramics, in electronic packaging, and for the properties of oxide scales on metals (or metallic alloys) formed after high-temperature corrosion.

Fracture in metal–ceramic composites

Composites Science and Technology, 2004
This research focuses on fracture mechanisms in metal–ceramic composites. Two co-continuous composites, Cu/Al2O3 and Al/Al2O3 and a metal–matrix composite Al/SiC were studied. It was found that each composite displayed a different fracture mechanism. The crack propagation inside the metal–matrix composite was dominated by the Al matrix characteristics.

Microdesigning of Ceramic-Metal Composites

1987
Microdesigning of ceramic-metal composites is described in chemically compatible and incompatible systems. The problems associated with microstructural design are addressed with respect to capillarity and reaction thermodynamics. The B4C−Al system is used to illustrate the formation of tailored microstructures which exhibited average fracture strength ...

Micrograded ceramic-metal composites

Journal of the European Ceramic Society, 2019
Abstract The article shows new designed cermets and processes concerning primary to applications as thermal insulation materials with low emissivity. A new projected microstructure was obtained where dense regions (micropellets) rest inside the main porous pellet.

Metal–Ceramic Composite Actuators

Journal of the American Ceramic Society, 1992
A new type of actuator composed of metal (brass) end caps and piezoelectric ceramics has been developed as a displacement transducer. Shallow cavities positioned between the metal caps and the central ceramic disk convert and amplify the radial displacement of the piezoelectric ceramic into a large axial motion of the metal end ...

Ceramic-metal composite actuator

Ferroelectrics, 1994
The main objective of this work was to develop a new type of actuator. It consists of a piezoelectric ceramic disk or multilayer stack and two metal end plates with a crescent-shaped cavity on the inner surface. The plates are used as mechanical transformers for converting and amplifying the lateral displacement of the ceramic into a large axial motion

Design of metal ceramic composites

International Journal of Materials Research, 2006
Abstract The reinforcement of light metal alloys with ceramic preforms offers a wide range of possibilities to improve mechanical and thermal properties and makes them usable for technical application. Starting with the Lokasil® composite material, different metal ceramic materials were created under serial-like conditions with the aim ...
