temperature) should be about __ times the melting of the metal.
2% - ANSWER-Generally speaking, steels are Fe-C alloys with less than about __
carbon content?
Additive manufacturing - ANSWER-Which one is the newest member as the five basic
material processing families?
Austenite - ANSWER-In the Iron Carbon equilibrium diagram, which of the following
phases exists at a high temperature (>912 C) environment?

cup (as shown to the right). Technically speaking, this process (of transforming the disk
into a cup) should be called __________.
beyond its ultimate tensile strength. - ANSWER-In shearing, the metal is deformed
___________
beyond its yield strength but below its ultimate tensile strength. - ANSWER-In bending,
the metal is deformed ___________
blanking - ANSWER-In the video "How It's Made - Aluminum Cans," the aluminum
sheet is fed into to a press that punches out round pieces that will be formed into cans.
This process is called
Body-centered cubic - ANSWER-Generally speaking, which structure has a better
strength?
Both allowance and tolerance - ANSWER-____________ must be specified if one is to
obtain the desired fit between mating parts.
Cannot Tell - ANSWER-Suppose surface A has roughness Rmax = 1 μm and surface B
has roughness Ra = 0.75 μm. Which surface is smoother?
Carbide steel - ANSWER-Which of the following will be the best material to make gage
blocks to maintain their high accuracy for everyday use in manufacturing plants?
, Cast Iron - ANSWER-Low Ductility Metal
casting - ANSWER-Among the following four groups of manufacturing processes, which
one will most likely involve molten metal?
casting, material removal, deformation and consolidation. - ANSWER-There are four
"families" of materials processing processes. They are __________________.
cold working - ANSWER-Which category of metal forming processes generally
produces better surface finish?
Composites - ANSWER-On Boeing 787 airplanes, which type of material is used the
most?
Cope; Drag - ANSWER-In a two-part sand casting mold, the top part is called a ____
and the bottom is called a ____.
crystalline - ANSWER-Atoms in most metals have a ____ structure.
Cu+Ni - ANSWER-What materials are used to mint the 25 cent coin?
Define Annealing - ANSWER-to soften strain (work) hardening metal; max softness and
ductility, uniform properties; Time and Energy consuming
Define Normalizing - ANSWER-to soften strain (work) hardening metal; allowed to cool
in still air; structure and strength depend on cooling rate
Define Quenching - ANSWER-dipping metal into some form liquid to cool it (water with
salt, water, synthetic polymers, oil, air)
Define Tempering - ANSWER-Reheated to below lower transformation temperatures;
Reduces brittleness, strength, and hardness, provides ductility; air cooling
defined by product engineers - ANSWER-Tolerance is usually
Deformation - ANSWER-Extrusion belongs to which one of the four families?
Deformation (Forming) - ANSWER-Many processes are used in manufacturing of
aluminum cans. Most of these processes belong to the family of _____________.
Die - ANSWER-Cast iron is not ideal for which of the casting method?
Die Casting - ANSWER-Which one of the following casting methods is not usually
applied to cast iron with low fluidity?
