Which of the following is true?

Detailed Solution: Question 3

Explanation: In annealing, the furnace is switched off and component cools slowly. In normalising, component is air cooled.

Test: Plain Carbon Steels - 2 - Question 4
Save

 Quenching

Detailed Solution: Question 4

Explanation: During quenching, component is rapidly cooled which leads to formation of martensite. Hence hardness increases.

Test: Plain Carbon Steels - 2 - Question 5
Save

Tempering involves

Detailed Solution: Question 5

Explanation: Tempering involves reheating the quenched product to a temperature less than transformation range. It improves ductility and reduces brittleness.

Test: Plain Carbon Steels - 2 - Question 6
Save

Silicon addition in spring steel increases its toughness.  

Detailed Solution: Question 6

Explanation: Silicon addition increases strength without lowering the ductility.

Test: Plain Carbon Steels - 2 - Question 7
Save

Nickel addition in alloys

Detailed Solution: Question 7

Explanation: Nickel addition increases toughness by limiting grain growth.

Test: Plain Carbon Steels - 2 - Question 8
Save

 Flame hardening involves

Detailed Solution: Question 8

Explanation: Flame Hardening is a process of heating the surface with a flame above critical temperature and then quenching it.

Test: Plain Carbon Steels - 2 - Question 9
Save

 Induction hardening process involves

Detailed Solution: Question 9

Explanation: Heating can only be done in presence of alternating current and not constant current.

Test: Plain Carbon Steels - 2 - Question 10
Save

Case carburising involves

Detailed Solution: Question 10

Explanation: Case carburising involves introducing carbon at surface layer. Medium can be liquid, solid or gas and high case depths are possible.
