Chapter:

6. Major constituent of gun metal is ________

Copper Nickel Iron Zinc

Copper

Gun metal (also known as red brass) contains 83% Cu and 2% Zn and 10% Sn.

Hint Answer

7. Red hardness of an alloy steel can be improved by adding ________

Tungsten Vanadium Manganese Titanium

Tungsten

Red hardness means capability of material to retain hardness at high temperature. It can be achieved for steel when alloyed high high melting metals like, tungsten, molybdenum, vanadium and chromium, etc.

Hint Answer

8. Tensile strength of an alloy steel can be improved by adding ________

Nickel Vanadium Manganese Titanium

Nickel

Nickel can improve tensile strength as well as toughness of alloy steel. Small additions of niobium (Nb) also increases tensile strength of carbon steel.

Hint Answer

9. Major constituent of Constantan alloy is ________

Copper Nickel Iron Zinc

Copper

Constantan (also known as Eureka/Ferry) contains 60% Cu and 40% Ni. It finds its mainly in rmocouples and has strong negative seebeck coefficient above 0^oC.

Hint Answer

10. Cast iron is a product of _______

Cupola Bessemer converter Open hearth furnace Blast furnace

Cupola

The cupola furnace (a modified blast furnace) can be used to melt cast irons, bronzes, etc. Cast irons have a carbon content of 2-4%, and have low melting temperatures, which makes m easily castable.

Hint Answer

11. What is approximate percentage of Lead in soft solder?

60 50 90 99.02

50

Soft solder is eutectic alloy of 50% Pb and 50% Sn, having a melting point of 450^oC.

Hint Answer

12. Major constituent of Nichrome is _________

Copper Nickel Iron Zinc

Nickel

Nichrome contains 80% Ni and 20% Cr. Nichrome mostly used as a resistant wire and in dental fillings.

Hint Answer

13. Abrasion resistance of an alloy steel can be improved by adding _______

Tungsten Vanadium Manganese Chromium

Chromium

Chromium is generally added to steel to increase corrosion resistance and oxidation, to increase hardenability, to improve high-temperature strength, and to improve abrasion resistance in high-carbon compositions. The formation of hexagonal Cr₇C₃ is responsible for this abrasion resistance to steel.
