WebHot working usually results in the refinement of grain structure whereas cold working merely distorts the grains and does little towards reducing its size. As the handling of … WebDec 28, 2009 · Fabrication: Whether a metal has been hot rolled, cold rolled, cold drawn cast, or forged will affect its grain size, ductility, strength, hardness, structure-and therefore-its machinability. The term "wrought" refers to the hammering or forming of materials into premanfactured shapes which are readily altered into components or products using ...

Hot working improves the engineering properties of the workpiece because it replaces the microstructure with one that has fine spherical shaped grains. These grains increase the strength, ductility, and toughness of the material. [2] The engineering properties can also be improved by reorienting the … See more In metallurgy, hot working refers to processes where metals are plastically deformed above their recrystallization temperature. Being above the recrystallization temperature allows the material to … See more The lower limit of the hot working temperature is determined by its recrystallization temperature. As a guideline, the lower limit of the hot working temperature … See more • Rolling • Hot spinning • Extrusion • Forging • Drawing • Rotary piercing See more The advantages are: • Decrease in yield strength, therefore it is easier to work and uses less energy or force See more WebDuring hot metal working, distorted grain structure and strain hardening produced by deformations are rapidly eliminated due to the formation of new strain-free grain (a result of recrystallization). The maximum … WebEFFECTS OF COLD WORKING ON MICROSTRUCTURAL AND MECHANICAL ... mode (13- 16), with probably a synergetic effect of hydrogen embrittlement (13). ... 20%), issued from the heat 2, has a homogeneous structure with a very fine grain (Gafnor : 10) with au inter- and intra-granular precipitation of 6 phase.
