Before revision: Advantages & disadvantages aman rizvi The advantages are: Decrease in yield strength, therefore it is easier to work and uses less energy or force Increase in ductility Elevated temperatures increase diffusion which can remove or reduce chemical inhomogeneities Pores may reduce in size or close completely during deformation In steel, the weak, ductile, face-centered-cubic austenite microstructure is deformed instead of the strong body-centered-cubic ferrite microstructure found at lower temperatures Usually the initial workpiece that is hot worked was originally cast.
