Question Number 1: what is heat treatment and why is it done?
Answer: Heat treatment can be defined as a combination of processes or operations in which the heating and cooling of a metal or alloy is done in order to obtain desirable characteristics without changing the compositions. Some of the motives or purpose of heat treatment are as follows:
In order to improve the hardness of metals.
For the softening of the metal.
In order to improve the mach inability of the metal.
To change the grain size.
To provide better resistance to heat, corrosion, wear etc.
Question Number 2: Why do heavy vehicles use diesel engine?
Answer: The compression ratio of diesel engine is higher than the petrol engine, the reason for producing higher torque. The efficiency of diesel engine increases with load. Diesel produces slow energy on burning of fuel and the efficiency of the engine increases with load which is why diesel engine is suitable and largely used for heavy vehicles
Question Number 3: what are types of heat treatment?
Answer: Heat treatment is generally performed in the following ways:
