Modifying Metals_Definitions Flashcards
Annealing
Heating a metal to a moderate temperature and then allowing it to cool slowly to make it softer and more ductile
Crystal
A solid made up of atoms or molecules arranged in a repeating three dimensional pattern
Heat Treatment
Heating a metal in different ways to alter its structure and physical properties
Interstitial Alloy
An alloy made by adding smaller atoms to a metal
Quenching
Heating a metal to a moderate temperature and then cooling it rapidly to make it harder and more brittle
Substitutional alloy
An alloy made from elements of similar chemical properties
Tempering
A process in which a metal that has been quenched is warmed again to a lower temperature to reduce its brittleness but to retain its hardness
Work Hardening
The increase in strength that results from processes such as hammering, rolling and drawing a metal
