In materials science, a metal matrix composite (MMC) is a composite material with fibers or particles dispersed in a metallic matrix, such as copper, aluminum, or steel.The secondary phase is typically a ceramic (such as alumina or silicon carbide) or another metal (such as steel [1]).
Aluminium oxynitride is the hardest polycrystalline transparent ceramic available commercially. [2] [needs update] Because of its relatively low weight, distinctive optical and mechanical properties, and resistance to oxidation or radiation, it shows promise for applications such as bulletproof, blast-resistant, and optoelectronic windows. [4]
Fracture surface of a fiber-reinforced ceramic composed of SiC fibers and SiC matrix. The fiber pull-out mechanism shown is the key to CMC properties. CMC shaft sleeves. In materials science ceramic matrix composites (CMCs) are a subgroup of composite materials and a subgroup of ceramics. They consist of ceramic fibers embedded in a ceramic matrix.
Ceramic" may be used as a noun in the singular to refer to a ceramic material or the product of ceramic manufacture, or as an adjective. Ceramics is the making of things out of ceramic materials. Ceramic engineering, like many sciences, evolved from a different discipline by today's standards.
It is a composite ceramic material with zirconia grains in the alumina matrix. It is also known in industry as ZTA. Zirconia aluminia (or zirconia toughened alumina), a combination of zirconium oxide and aluminum oxide, is part of a class of composite ceramics called AZ composites. Noted for their mechanical properties, AZ composites are ...
AlSiC, pronounced "alsick", [1] is a metal matrix composite consisting of aluminium matrix with silicon carbide particles. It has high thermal conductivity (180–200 W/m K), and its thermal expansion can be adjusted to match other materials, e.g. silicon and gallium arsenide chips and various ceramics.
Aluminium magnesium boride or Al 3 Mg 3 B 56, [1] [2] [3] colloquially known as BAM, is a chemical compound of aluminium, magnesium and boron.Whereas its nominal formula is AlMgB 14, the chemical composition is closer to Al 0.75 Mg 0.75 B 14.
Mullite is a compound of alumina and silica, with the formula 3Al2O3-2SiO2. It has a low density, along with good mechanical properties, high thermal stability, low thermal conductivity, and is corrosion and oxidation resistant. However, it suffers from crystallization and volume contraction above 800 °C, which leads to cracking and delamination.
