Metals Test

Materials science is the study of solid stuff

Steel is a substitutional alloy.

One of the biggest advantages to many metals, like tin, are their recyclability.

The effects of heat treating steel vary depending on how much carbon is in the iron.

Defects in metals will always have a negative effect on its properties.

How many different types of processing does a typical metal object undergo?

• zero

• one

• multiple

• eleven billion

Metals have a(n) ____________________ structure.

• amorphous

• crystalline

• random

• porous

Metals have these types of bonds

• metallic

• ionic

• covalent

• intermolecular forces

Two types of alloys are ______________ and _______________.

• synthetic & natural

• interstitial & substitutional

• ferrous & non-ferrous

• crystalline & amorphous

The bounce in the iron wire demo was caused by

• the solid state phase change from FCC back to BCC as it cooled down

• carbon evaporating out of the wire

• the amorphous structure

• the change in magnetism
