I would like to know when we do quenching does it lead to amorphization always? if yes then what leads this process to occur? how quenching helps in single phase formation?
Quenching does cause any additional processes. Contrarily, it fixes the positions that atoms had at the high temperature. If you start the quenching from the liquid state, the chaotic arrangement of the atoms will be preserved and the resulting solid will be amorphous. It can be also possible for example to quench the high-temperature phases or the solid solutions that exist at the high temperatures but become unstable at low temperatures.

QUENCHING KEEPS GRAINS SMALLER THAT MAKES MATERIAL HARDER. QUENCHING ALSO KEEPS ALLOY IN SOLD SOLUTION.
The concept of glass forming ability (GFA) may possibly be found of some interest with regards to this query; cf.: https://www.researchgate.net/post/What_is_relationship_between_the_glass_forming_ability_GFA_and_the_viscosity_of_the_corresponding_liquid_phase?exp_tc=tprc https://www.researchgate.net/post/Critical_cooling_rate_and_critical_thickness_to_describe_the_glass_forming_ability_GFA?exp_tc=tprc
Quenching is carried out in order to freeze the structure or to keep the structure with out getting disturbed much.
Yes Sir. Again the question comes the structure will be affected by amorphization that will also arise during quenching.So how to understand and overcome this effect when I want the structure to be stable and also the crystallinity?
