- Mechanical properties for example ductility, toughness, percentage reduction in area, percentage elongation and resistance to shock and vibration are better due to the refinement of grains.

Advantages
Hot-Working Processes - Extrusion
Extrusion
Points : Extrusion, Definition Definition The extrusion process is now used for shaping a variety of ferrous and non-ferrous metals and alloys. Its most important feature is that we are able to force the metal through a die, and, in a single process from the cast billet, to obtain quite complicated sections of tolerably accurate dimensions.

Hot-Working Processes - Hot processing
Hot processing
Points : Hot processing, Definition Definition Hot-pressing is a development of the drop-forging process, but is generally applied in the manufacture of more simple shapes. The hammer of drop-forging is replaced by a hydraulically driven ram, so that, instead of receiving a rapid succession of hammer blows, the metal is gradually squeezed by the static pressure of the ram. This downwards thrust is sometimes as great as 100 MN.

Hot-Working Processes - Heading
Heading
Points : Heading, Definition Definition ‘Heading’ or ‘up-set’ forging is employed extensively for the manufacture of bolts, rivets and other components, where an increase in diameter is necessary without loss of strength and shock-resistance.

Hot-Working Processes - Drop-forging
Drop-forging
Points : Drop-forging, Definition Definition If a large number of identical forged components are required, then it is economically preferable to make then by a drop-forging process. In this process a shaped die is used, one half being attached to hammer and the other half to the anvil. With complex shapes a series of dies may be used.

Hot-Working Processes - Forging
Forging
Points : Forging, Definition Definition Forging metals by hand at least six thousands years ago but there is evidence that pre-historic man was using this type of process to fashion copper some two thousand years earlier. Hand forging is still used to a limited extent by the smith but most modem forging is power-assisted.

Hot-Working Processes - Hot-rolling
Hot-rolling
Points : Hot-rolling, Definition Definition Hot-rolling is universally employed in the reduction of large steel ingots to sections, strip, sheet and rod of various sizes. In fact the only conditions under which cold-work is applied to steel are when the section is too small to retain its heat, or when a superior finish is required in the product.
