Annealing, in metallurgy and materials science, is a heat treatment wherein a material is altered, causing changes in its properties such as strength and hardness. It is a process that produces conditions by heating to above the recrystallization temperature and maintaining a suitable temperature, and then cooling.

It was taught in class 10th.

ANNEALING :

Annealing is nothing but hardening something by heating. It may vary for different purposes as follows..

-> Mettalurgy - Annealing : is a heat treatment wherein a material is altered, causing changes in its properties such as strength and hardness.

-> Glass - Annealing : Heating a piece of glass to remove stress.

-> Biology - Annealing : DNA or RNA pairing by hydrogen bonds to a complementary sequence, forming a double-stranded polynucleotide.

In this way the meaning of Annealing differs depending upon the usage..

hope the info. helps..

Annealing:

Annealing terminology is widely used in different fields of science.

Annealing in terms of biology is binding or pairing of DNA or RNA sequence to H-bonds of complementary strand forming double stranded structure. It is step widely used in PCR reactions.

Annealing in terms of metallurgy is a heat treatment that alters the microstructure of a material causing changes in properties such as strength and hardness and ductility.

Knowledge annealing is a network-based information system in which all users of the system are permitted to change the system at will.

Dictionary Mean :-

Annealing is a Noun

Its Mean hardening something by heat treatment

Its synonym can be tempering

Bookish Definition :-

The process used to render glass, iron, etc., less brittle, performed by allowing them to cool very gradually from a high heat

Annealing is the process that takes place within a kiln, during a soak cycle. During this process, the temperature is slowly reduced so that the “stress” on the molecular level is removed the beads

Below is the Annealing Machine

Hiiiii,

What does Annealing mean?

Answer: -

1. Annealing is the process that takes place within a kiln, during a soak cycle.

2. During annealing process, the temperature is slowly reduced so that the “stress” on the molecular level is removed the beads.

3. Annealing means the burning of metallic colors into glass, earthenware, etc.

4. To heat glass or metal and then cool slowly to prevent brittleness.


All the Best

Annealing is a NOUN..

Annealing is process in which metal, alloy, or other material are heating to a temperature, holding for a certain time, and then cooling to room temperature, done to improve ductility and reduce brittleness.

This is used in industries before all the metal to be use..

Annealing is also done for reduce of internal stresses in metal and glass.Annealing is a chemical process..

the meaning of annealing is:
1.To subject (glass or metal) to a process of heating and slow cooling in order to toughen and reduce brittleness.
2.To strengthen or harden.

Annealing mean

Definition: Heating steel to, and holding at a suitable temperature, followed by relatively slow cooling.

- The purpose of annealing may be to remove stresses, to soften the steel, to improve machinability, to improve cold working properties, to obtain a desired structure.

-The annealing process usually involves allowing the steel to cool slowly in the furnace.
