An alloy is a mixture of metals or a mixture of a metal and another element.Alloys are defined by metallic bonding character.An alloy may be a solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions). Intermetallic compounds are alloys with a defined stoichiometry and crystal structure.he term alloy is used to describe a mixture of atoms in which the primary constituent is a metal. The primary metal is called the base, the matrix, or the solvent. The secondary constituents are often called solutes.
Marl or marlstone is a calcium carbonate or lime-rich mud or mudstone which contains variable amounts of clays and silt.
Kevlar is a material formed by combining para-phenylenediamine and terephthaloyl chloride. Aromatic polyamide (aramid) threads are the result.They are further refined, by dissolving the threads and spinning them into regular fibres. When woven, Kevlar forms a strong and flexible material.If layers of the woven Kevlar are combined with layers of resin, the resulting ârigidâ material is light and has twenty times the strength of steel. It is also superior to specialist metal alloys.hen woven, Kevlar forms a strong and flexible material.
