ROCKWELL TEST PRACTICE TEST BANK
2026 TESTED QUESTIONS WITH ANSWERS
GRADED A+
⩥ cementite. Answer: iron carbide (Fe3C) as a phase in steel
⩥ ferrite. Answer: body-centered cubic iron
⩥ pearlite. Answer: a phase in steel composed of alternating layers of
Fe3C (cementite) and ferrite
⩥ eutectic. Answer: a phase with a single melting temperature
(liquidus and solidus lines meet-not at the axis)
⩥ eutectoid. Answer: a solid phase with a single transition temperature
to another solid
⩥ allotropic. Answer: material has the ability to change crystal structure
⩥ rimmed steel. Answer: slightly deoxidized steels that solidify with an
outer shell on the ingot which is low in impurities and very sound; can
retain a good finish, even after severe deforming because of the surface
cleanliness
, ⩥ killed steel. Answer: strongly deoxidized, usually by chemical
additions to the melt
⩥ galvanized. Answer: zinc-coated steel products; the zinc is applied by
hot dipping
⩥ sheet. Answer: rolled steel primarily in the thickness range of 0.010 to
0.25 in and with a width of 24 in or more
⩥ bar. Answer: hot- or cold-rolled rounds, squares, hexes, rectangles and
small shapes; round bars can be as small as 0.25 in; flats can have a
minimum thickness of .203 in; shapes have a maximum dimension less
than 3 in
⩥ coil. Answer: rolled steel in the thickness range of sheet or strip
⩥ flat wire. Answer: small hot- or cold-rolled rectanges,often by cold-
reducing rounds to rectangular shape
⩥ wire. Answer: hot- or cold-drawn coiled rounds in varying diameters,
usually not exceeding 0.25
