Question

which heat treatment process is to remove extreme brittleness caused by hardening?​

Answer 1

Answer:

The process of Annealing is used.

Explanation:

Heat treatment has mainly stages such as

Annealing

Hardening

Tempering

Normalizing​.

All of these stages have their own specific objective and function.

In the process of hardening, metal is quenched so that it gets hardened which in return also increases its brittleness.

The opposite treatment for this is the stage of annealing. In this process,

metals are heated to a specific temperature after which they are cooled down. Metals tend to become brittle after cold working and this process is conducted after cold working conditions.

Annealing is known to have been used for the purpose of removing the effects of solution heat treatment. This is done to improve machining or working qualities.

Answer 2

Tempering ‘heat treatment process’ is to remove ‘extreme brittleness’ caused by hardening.

Explanation:

• Tempering is a ‘heat treatment process’ which helps in increasing the tensile strength of the metals. On increase in the tensile strength there is decrease in the brittleness.  

• Also the metals become malleable and ductile, that is they can be heated into plates or they can be drawn into wires.  

• Thirdly the metals can be made to resist the extremes of temperature. This process is usually done in the ‘manufacture of steel’ and stainless steel where pig iron is converted into steel.
