austenite correct answers From 1394 to 912C (2541 to 1674F) pure iron assumes a face-
centered-cubic structure,in honor of the famed metallurgist Roberts-Austen of England. exhibits
the high formability that is characteristic of the face-centered-cubic structure and is capable of
dissolving more than 2% carbon in single-phase solid solution.
carbon equivalent correct answers CE = (wt% Carbon) + 1/3(wt% Silicon)
cast iron correct answers All alloys containing more than 2.11% carbon will experience the
eutectic reaction and are classified by this general term.
cementite correct answers
composition correct answers definable structure, a uniform and identifiable chemistry
cooling curve correct answers plotting the cooling history in the form of a temperature-versus-
time plot. the transitions in structure will appear as characteristic points, such as slope changes or
isothermal (constant-temperature) holds.
cored structure correct answers
Curie point correct answers
delta-ferrite correct answers
diffusion correct answers the process by which atoms migrate through the crystal lattice given
sufficient time at elevated temperature.
equilibrium phase diagram correct answers is a graphic mapping of the natural tendencies of a
material or a material system, assuming that equilibrium has been attained for all possible
conditions.
eutectic structure correct answers
eutectoid correct answers
ferrite correct answers
freeze drying correct answers A transition will be encountered where solid goes directly to gas
without melting (sublimation). employed in the manufacture of numerous dehydrated products.
freezing range correct answers Instead of possessing a distinct melting point or freezing point,
this material is said to have
graphite correct answers
,hypereutectoid steel correct answers
inoculation correct answers
interfases correct answers distinct boundaries, that separate phases from other different phases.
iron-carbon equilibrium phase diagram 115 Fig. 5-10 115 correct answers
lamellar structure correct answers
lever law correct answers If the point lies in a two-phase region, the relative amounts of the two
components
liquidus correct answers the lowest temperature at which the material is totally liquid,
macrosegregation correct answers
maximum solubility correct answers 183C,
monotectic correct answers
nonstochiometric intermetallic compound correct answers
partial solid solubility correct answers Many materials do not exhibit complete solubility in the
solid state. Each is often soluble in the other up to a certain limit or saturation point, which varies
with temperature.
perlite correct answers
peritectic correct answers
peritectoid correct answers
phase correct answers simply a form of material possessing a characteristic structure and
characteristic properties. Uniformity of chemistry, structure, and properties is assumed
throughout a phase.
pressure-temperature equilibrium phase diagram (P-T) Fig. 5-1 correct answers
primary phase correct answers
proeutectoid cementite correct answers
proeutectoid ferrite correct answers
, proeutectoid phase correct answers
silicon correct answers
solidus line correct answers The lower line, denoting the highest temperature at which the
material is completely solid,
solubility limit correct answers the maximum concentration of solute that may be added without
forming a new phase
solute correct answers A substance that is dissolved in a solution.
solvus correct answers If there is a limit to this solubility, there will be line in the phase diagram,
denoting the conditions of saturation where the single-phase solid solution becomes a two-phase
mixture.
steel correct answers
stoichiometric intermetallic compound correct answers
syntectic correct answers
tempetature-composition phase diagram correct answers
three-phase reaction correct answers
tie-line correct answers an isothermal (constant-temperature)
line drawn through the point of consideration, terminating at the boundaries of the single-phase
regions on either side.
assembly correct answers represents the organized activities that convert raw materials into
salable goods.
heat treatment correct answers the heating and cooling of a metal for the specific purpose of
altering its metallurgical and mechanical properties. basic manufacturing process
sustaining technology correct answers serve to continually bring more value to the consumer of
existing products and services.
storage correct answers nothing happens intentionally to the product or part except the passage of
time.
production system correct answers system includes the manufacturing system plus all the other
functional areas of the plant for information, design, analysis, and control. These subsystems are
connected by various means to each other to produce either goods or services or both.
