Metallurgy Quiz

What is a ferrous metal?

• A metal that contains iron

• A metal that does not contain iron

• A metal that contains carbon

• A metal that is brittle

What is the carbon content range in carbon steel by weight?

• 0.1-0.5%

• 0.5-2.1%

• 2.1-3.5%

• 3.5-5.0%

What is the definition of brittle material?

• A material that can be stretched without breaking

• A material that tends to break with little to no elastic deformation

• A material that can return to its original shape after deformation

• A material that can withstand high temperatures

What is plastic deformation?

• Temporary distortion that occurs when stress is applied to a material

• Permanent distortion that occurs when stress is applied to a material

• The ability of a material to withstand a twisting load

• The maximum amount of pulling stress a material can withstand before breaking

What is tensile strength?

• The maximum amount of pulling stress a material can withstand before breaking

• The maximum amount of stress a material can withstand before plastic deformation takes place

• The maximum amount of shear stress a material can withstand before failure

• A material's ability to withstand a twisting load

What is fatigue in materials?

• The ability of a material to withstand high temperatures

• The most common type of mechanical failure due to repeated stresses

• The act of pressing a material into a smaller space

• The act of pulling on a material to stretch it out

What is the difference between mechanical properties and physical properties?

• Mechanical properties are observable, while physical properties describe how a material responds to different stresses

• Physical properties are observable, while mechanical properties describe how a material responds to different stresses

• Both mechanical and physical properties are observable

• Both mechanical and physical properties describe how a material responds to different stresses

The maximum amount of stress a material can withstand before plastic deformation (permanently bending) takes place

• hardness

• Compression

• Yield Strength

• Tensile strength

The word "tensile" means

• Pulling

• Pushing (smooshing together)

• Twisting

• Breakdancing

Hardness is:

• A measure of how resistant a material is to denting or scratching

• A material's resistance to deformation

• The amount of twist a bar can withstand

• The amount of compression a bar can withstand before breaking
