Class Vocabulary

Vocabulary TermDefinition
abrasive A material or tool consisting of hard particles used to wear down, rub away, or machine material. Common abrasives are ceramic materials.
advanced composite A composite consisting of relatively expensive materials that is designed for special applications.
alloy A metal consisting of two or more materials. One of these materials must be a metal.
alloy steel Steel that contains added materials that change the property of the metal. Common alloy elements include chromium, manganese, molybdenum, and nickel.
brittle A material's unwillingness to be drawn, stretched, or formed. Brittle metals tend to break if subjected to these forces.
ceramic A hard, brittle material that can withstand high temperatures and resist corrosion.
chromium A shiny, hard, steel-gray metal used in ferrous alloys to add hardness and wear resistance to steel. Stainless steels contain large percentages of chromium.
composite A material that is a combination of other materials from two or more of the following groups: metals, plastics, and ceramics.
corrosion The deterioration of a metal or ceramic.
density The relative "compactness" of a material. Density is the mass of a material per unit volume.
elastomer A group of plastics that can stretch and then return to the original shape without permanent deformation.
engineered To intentionally apply science and technology in order to design, create, or improve a product.
ferrous metal A metal that contains iron. The most common ferrous metal is steel.
fibrous composite A composite that consists of thin slivers of one material embedded in another material.
hardness The ability of a material to resist penetration, indentation, or scratching.
internal structure The arrangement of particles, or atoms, within a material.
laminar composite A composite that consists of one layer of material binded on top of another material.
manufacturing The process of producing and shaping a product on a large scale, often through the use of large machinery.
mechanical properties The collection of properties that describe a material's ability to compress, stretch, bend, scratch, dent, or break.
melting point The temperature necessary to change a solid to a liquid.
metal A hard, strong material that conducts electricity and heat, is shiny when polished, and can be bent and formed into shapes.
nonferrous metal A metal that does not intentionally contain iron.
particulate composite A composite that consists of tiny particles of one material embedded in another material.
physical properties The collection of properties that describe how a material reacts to forces other than mechanical forces. Melting, freezing, thermal conductivity, and electrical conductivity are all physical properities.
plastic A lightweight material that typically resists corrosion and is easily shaped.
polymer The technical term for plastics.
properties A characteristic of a material that distinguishes it from other materials.
pure metal A metal that does not intentionally contain any other material.
stainless steel An alloy steel that is designed to resist corrosion.
steel A metal consisting of iron and carbon, usuallly with small amounts of manganese, phosphorus, sulfur, and silicon as well.
structural composite A composite consisting of common materials that are relatively inexpensive.
thermoplastic A group of plastics that can be softened by heat, hardened by cooling, and then softened by heat over and over again.
thermosetting plastic A group of plastics that is permanently hardened by cooling.
tool steel A type of steel designed with high wear resistance, toughness, and strength.
