Materials And Fastening Devices Flashcards
Duct utility refers to
Amount a metal can stretch beyond it’s elastic limits without breaking or cracking
An alloy is
A mixture of two or more chemicals elements one of wich being metal
Toughness is
A resistance to fracture or the amount of energy a substance will absorb
If it’s malleable it is
Shaped or moulded easily
Elasticity is
The maximum stretch a material can withstand and still return to it’s original shape
Elastic limit refers too?
The amount of stress a material can receive and still return to it’s original shape
What is tensile strength
The load in psi that a material will sustain before fracturing
Hardness refers to
The ability of a material to resist denting
What is work hardening?
Work hardening is an increase in hardness and strength of a metal from deformation at low temps
Annealing is
The process of heating and slowly cooling the metal toughen and reduce brittleness
To quench metal is to
Dunk hot metal in liquid
Tempering is
A heat treating process to reduce hardness promote toughness
Ferrous metals are
Metals consisting of an iron base
Non ferrous metals are?
Aluminum. Brass copper. Lead. Magnesium. Nickel. Silver. Gold
Natural rubber is transformed by the process of
Vulcanizing
