1

When a piece of sheet metal is pulled from each end, the resulting force is

tension

2

The measure of strength of a metal to resist overall deformation

yield strength

3

The metal's ability to resist being pulled apart is called it's:

tensile strength

4

The ability of a metal to resist any crushing or excessive compression is called the metal's:

bearing strength

5

The ability for a metal's surface to resist cutting, abrasion or penetration is called:

hardness

6

The material's ability to be bent, formed or shaped is called:

malleability

7

The ability of metal to be drawn into wire stock extrusions, or rods is called the metal's:

ductility

8

The material's tendency to break or shatter when exposed to shock

brittleness

9

The property which enables a metal to carry heat or electricity

conductivity

10

The property of metal to expand when heated and shrink when cooled, at a predictable and specific temperature

Coefficient of expansion

11

The point at which a metal does not return to it's original shape after a deforming force is removed

Elastic limit

12

A material's ability to resist tearing or breaking when it is bent or stretched

toughness

13

The ability of a metal to be joined by heating and melting

Fusibility

14

A material's mass per unit volume

Density

15

Objects formed by physically working the metal into shape

Wrought

16

Objects formed by pouring molten metal into molds

Cast

17

The process of forming metal at an elevated temperature when it is in its annealed state

Hot-working

18

After hot-working an ingot , the process that must be undertaken to finish it and the reason why

Quenching , since the surface is solid but the core may still be molten
