Properties Of Materials Flashcards
Enables a material to resist penetration, wear, or cutting action.
Hardness
Ability of a material to withstand forces which tend to deform the metal in any direction, or ability of a material to resist stress without breaking.
Strength
The ability of an object or material to be stretched and recover its size and shape after deformation.
Elasticity
The property of a metal which allows it to be reshaped.
Plasticity
The property which allows metal to be drawn into thinner sections without breaking.
Ductility
The characteristic of a material that allows it to be streched, or shaped by beating with the hammer or passing through rollers without breaking.
Malleability
The property of a metal which allows it to be deformed without breaking.
Toughness
The property of a metal to break when deformed or hammered. It is the resistance to change in the relative position of the moleculed within the material.
Brittleness
The characteristic of a material which makes it possible for it to transmit heat, or electrical conduction.
Conductivity
The property of metal that enables it to withstand force over a period of time.
Durability
A metal's tendency to return to its original shape after normal stretching, and bending.
Elasticity
Property of a metal to expand when heated and shrink when cooled.
Thermal Expansion
The amount of expansion or contraction is predictable at specific temperatures.
Coefficient of Expansion
A material's ability to resist tearing or breaking when it is bent or stretched.
Toughness
The ability of metal to be joined by eating and meating.
Fusibility
A material's mass per unit volume.
Density
4 Types of Strengths
1. Tensile Strength
2. Yield Strength
3. Shear Strength
4. Bearing Strength
The ability to withstand tension.
Tensile Strength
The ability of a metal to resist deformation.
Yield Strength
The metal's ability to resist opposing forces.
Shear Strength
The ability of a joint to withstand any form of crushing or excessive compressive distortion.
Bearing Strength
Ability of a material to resist cutting, penetration, or abrasion.
Hardness
Ability of a material to be bent, formed, or shaped without cracking or breaking.
Malleability
Ability of a metal to be drawn into wire stock, extrusions, or rods.
Ductility
A material's tendency to break or shatter when exposed to stress.
Brittleness
The property which enables a metal to carry hear or electricity
