Material Properties - correct answer Ways to describe the behavior of material in response to physical forced Metal properties - correct answer crystalline structures Strong, hard, and ductile High electrical and thermal conductivity Opaque and reflective Cast metal - correct answer initial form is a casting Wrought Metal - correct answer Metal that has ...

Dislocations - a defect in the crystalline lattice. Dislocations move within a structure when stress is applied Pinning - inhibits the dislocation from moving within the structure resulting in the metal becoming stronger and more brittle. Precipitates - small atoms that fit within the vacant spaces between base metal atoms Entanglements - grains of a structure becoming stretched out. Created by cold working Tensile strength - A measure of how much stress from pulling, or tension, a materia...

Casting - A process in which metals are melted and poured into a die and solidified Expendable molds - Molds made of sand, plaster, ceramics Permanent molds - Molds made of metals with strength at high temperatures Composite molds - Molds made of two or more materials such as sand, graphite, and metal. Could have permanent and expendable portions Sand casting - Casting of material that is permeable, collapsible, strength, reusable, and has thermal stability Flask - Supports the mold Cope...

Ductility - Determines ability to shape sheet metal Shearing - An operation where a blank sheet metal is removed from a large sheet by subjecting it to shear stresses using a punch and a die. Slug - Piece of metal punched out. Can be reused or discarded. Punching - A shearing operation that separates a scrap slug from the work piece when the punch enters the die Punching keeps exterior, blanking keeps interior - Difference between punching and blanking Conventional Blanking - Similar to p...
