It is 0.45 times the melting point of the metal.

Recrystallization temperature in metal working can be defined as the temperature at which the plastic deformation takes place perfectly. The stresses induced during the process is are grater than the yield strength and less than the fracture strength.
650 degrees Celsius
Short bead as well as arc strikes create a sudden localized temperature increase to the metal and can cause cracking.
it is the resistance of material to impact(sudden) loading...or..it is the impact energy absorbed per unit area.
The hot working of steel can easily be defined as " the mechanical working on steel after heating above the recrystallization temperature" e.g. forging, hot pressing, drawing etc.
Grain size would generally increase during recrystallization with time spent at optimal crystallization temperature.
The term is used for character of steel, which become brittle at hot working temperature ie above 0.6 Tm (recrystallization temperature, where strain hardening is removed ) hot short hinders in hot working operation, often caused by the presence of sulphur in metal.

The recrystallization temperature for cop- per usually ranges from 200°C to 400°C.Highly purified copper will recrystallize at 100°C if annealed for a long time.
Plastic deformation of metals above the recrystallization temperature.
The coolness of the solution causes recrystallization. This is because the solute becomes solid at a higher temperature than the solvent.
One property that a solvent should have to be well suited for recrystallization of a particular compound is high solubility. It should also readily dissolve the organic compound at high temperature and precipitate the compound at low temperature.
Hot working of metals is defined as a process of forming metals by deformation at temperature above the recrystallization temperature.
