1What is the typical carbon content range in cast iron alloys used in foundry casting?
A.0.02% to 0.15%
B.0.20% to 0.60%
C.2.0% to 4.5%
D.6.67% to 10.0%
Explanation: Cast iron is defined as a ferrous alloy containing more than 2.0% carbon, typically ranging between 2.0% and 4.5% C along with 1.0% to 3.0% silicon. This high carbon content lowers the melting point (around 1150°C–1250°C) and improves fluidity during casting.
2Which microstructure feature gives gray cast iron its characteristic gray fracture surface and high vibration damping capacity?
A.Spheroidal graphite nodules
B.Flake graphite embedded in a metallic matrix
C.Iron carbide (cementite) network
D.Tempered carbon rosettes
Explanation: Gray cast iron contains carbon present predominantly in the form of uncombined graphite flakes. When fractured, the crack propagates along these graphite flakes, exposing them and imparting a dark gray appearance while providing exceptional damping capacity against mechanical vibrations.
3Which ferrous metal contains the lowest percentage of carbon and contains fibrous silicate slag inclusions?
A.Gray cast iron
B.Wrought iron
C.High-carbon tool steel
D.White cast iron
Explanation: Wrought iron is the purest commercial form of iron, containing less than 0.08% carbon along with 1% to 2% physically entrapped fibrous slag (iron silicate). This fibrous structure gives wrought iron high ductility, toughness, and superior corrosion resistance.
4Why is white cast iron extremely hard, wear-resistant, and virtually unmachinable?
A.All its carbon is present as free graphite flakes
B.All its carbon is chemically bound as iron carbide (cementite)
C.It contains high silicon and low manganese content
D.It is rapidly cooled in insulated sand molds for several days
Explanation: In white cast iron, cooling occurs rapidly or the silicon content is kept low, causing carbon to remain chemically combined with iron as cementite (Fe3C). Cementite is an extremely hard and brittle intermetallic compound, rendering white cast iron resistant to wear but unmachinable by standard tools.
5What chemical inoculant is added to molten cast iron immediately before pouring to produce ductile (nodular) iron?
A.Aluminum powder
B.Magnesium or Cerium alloy
C.Sulfur powder
D.Powdered charcoal
Explanation: Ductile or nodular cast iron is produced by adding a small amount of magnesium (usually as ferrosilicon-magnesium FeSiMg) or cerium to molten iron. Magnesium changes the surface tension of liquid iron, causing graphite to precipitate as rounded spheroids/nodules rather than sharp flakes.
6Malleable cast iron is produced by subjecting which type of raw casting to a prolonged annealing heat treatment?
A.Gray cast iron
B.Ductile cast iron
C.White cast iron
D.Low carbon steel
Explanation: Malleable cast iron is manufactured by heat treating (annealing) white cast iron castings at 850°C–950°C for 48–72 hours. This process breaks down the hard, brittle cementite (Fe3C) into ferrite and irregularly shaped clusters of graphite known as temper carbon.
7What is the carbon content range of medium-carbon steel commonly used for forged machine parts and structural castings?
A.0.05% to 0.25%
B.0.30% to 0.60%
C.0.70% to 1.20%
D.1.50% to 2.10%
Explanation: Medium-carbon steel contains 0.30% to 0.60% carbon. It balances strength, hardness, and ductility, making it suitable for automotive components, gears, shafts, rails, and structural machinery castings that require heat treatment.
8Which alloying element is primarily added to steel to provide high corrosion resistance and form stainless steel when present in quantities exceeding 11.5%?
A.Manganese
B.Chromium
C.Tungsten
D.Vanadium
Explanation: Chromium (Cr) forms a passive, self-healing oxide film of chromium oxide (Cr2O3) on the steel surface when present above 11.5–12%. This invisible layer prevents further oxidation and corrosion, creating stainless steel.
9In the iron-carbon equilibrium diagram, what is 'Pearlite' composed of?
A.A solid solution of carbon in alpha-iron (ferrite)
B.An alternate lamellar mixture of ferrite and cementite
C.A solid solution of carbon in gamma-iron (austenite)
D.A mechanical mixture of austenite and cementite (ledeburite)
Explanation: Pearlite is a two-phase lamellar (plate-like) microstructure formed by the eutectoid decomposition of austenite at 727°C (0.76% C). It consists of alternating layers of soft, ductile ferrite (87.5%) and hard, brittle cementite (12.5%).
10Why does gray cast iron exhibit superior castability compared to plain carbon steel?
A.It has a higher melting point and higher shrinkage rate
B.It has a lower melting point, higher liquid fluidity, and lower solidification shrinkage
C.It solidifies instantly without releasing latent heat
D.It expands by 20% during solid cooling
Explanation: Gray cast iron has a lower melting point (~1150°C vs steel ~1500°C) and higher fluidity due to eutectic carbon content (4.3% equivalent). Furthermore, graphitization during solidification causes a slight volume expansion that offsets metallic shrinkage, resulting in low net solidification shrinkage.
