all of these
The metal is subjected to mechanical working for Refining grain size and Reducing original block into desired shape and Controlling the direction of flow lines
recrystallisation temperature
Recrystallization is the process in which deformed grains of the crystal structure are replaced by a new set of stress-free grains that nucleate and grow until all the original grains have been consumed. The process is accomplished by heating the material to temperatures above that of crystallization.
above the recrystallisation temperature
Hot working process metals are plastically deformed above their recrystallization temperature. Being above the recrystallization temperature allows the material to recrystallize during deformation.
all of the above
During hot working of metals the Porosity of the metal is largely eliminated and Grain structure of the metal is refined and Mechanical properties are improved due to refinement of grains.
