TCS Interview Questions and Answers

Normalizing is a heat treatment process used to refine the grain structure of a material, improve its mechanical properties, and relieve internal stresses.

• Normalizing involves heating the material to a specific temperature range above the critical temperature, holding it at that temperature for a period of time, and then cooling it in still air.

• The temperature range for normalizing typically falls between 830°C to 950°C for most steels.

• The soaking time for normalizing varies ...read more

The iron-carbon diagram provides information about the percentage of carbon in steel, maximum percentage of carbon in iron, and the eutectic and eutectoid reactions.

• The percentage of carbon in steel typically ranges from 0.03% to 2.14%.

• The maximum percentage of carbon in iron is 6.67%.

• Cast iron contains a higher percentage of carbon, usually between 2.14% and 6.67%.

• The eutectic reaction occurs at a specific composition of 4.3% carbon and 1394°C, resulting in the formation of ...read more
