| What materials occupy the left side of the periodic table | metals |
| What is the property of a material that allows it to fail permanently or to exhibit plasticity without rupture while under tension | ductility |
| What is the property of a metal that allows it to resist being permanently deformed | hardness |
| This type of bonding consists of a transfer of electrons | ionic |
| This type of bonding shares electrons | covalent |
| This type of bonding has free electrons which makes the material a good conductor of heat | metallic |
| When an atom has this, it has the capacity to combine with other atoms to form a molecule | valence |
| What is the property of a material that allows it to be permanently when loaded in compression | malleabilty |
| What is the property of a material that will not deform plastically under a load | brittle |
| Describes an alloy containing a significant amount of iron | ferrous |
| A magnetic form of iron characterized by a body centered cubic crystal structure | ferrite |
| The heating of metal to soften it or reduce its strength | annealing |
| Slow plastic deformation in steel and most structural metals | creep |
| this type of material to be permanently deformed without failing | plasticity |
| Deforming a metal plastically at a temperature below its lowest recrystallization temperature is called | cold working |
| A process in which the distorted grain structure of metals that are subjected to mechanical deformation is replaced by a new strain-free grain structure during annealing | recrystallization |
| A method of metal working in which the metal is hammered into the desired shape, or is forced into a mold by pressure or hammering, usually after being heated to a plastic | forging |
| The softening process for ductile metals that have been work-hardened, during which metal is enclosed in a container with inert gas to avoid scaling and then heated to its recrystallizing temperature | bright annealing |
| Stresses induced within the structure of a metal by cold working, machining, and heat treatments and remaining in the metal after the treatment | residual stresses |
| The process of making a solid shape in a die by using punches to press together loose powder or a blend of | coining |
| A process of fusing metal powders into a solid piece by applying heat sufficient to bond, but not melt the particles | sintering |
| The distance that a cutting tools in either one revolution or in one minute in a machining operation | feed rate |
| The process of making a solid shape in a die by using punches to press together loose powder or a blend of powders | compaction |
| A machine tool that utilizes reciprocating motion of the cutting tool rather than the more common rotary motion to make repeated machining | shaper |
| A finishing process that utilizes a rotating & oscillating abrasive tool | honing |
| A nonmetallic conductor, usually a fluid, in which the electric current is carried by the movement of ions | electrolyte |
| An ionized gas of extremely high temperature achieved by passing an inert gas through an electric arc | plasma |
| Usually an inert gas used to displace air from around a weld zone, thus keeping the weld uncontaminated | shield gas |
| The thickness of the layer of material sheared from a workpiece by cutting tool in a machining operation | depth cut |
