WebJul 1, 2007 · It is often recommended that the maximum forging temperature for steels be at least 300°F below the melting point of the alloy. FLOW LOCALIZATION/SHEAR BANDS During deformation, material follows the path of least resistance, and it is subject to adiabatic (deformation) heating. WebA rough forging discontinuity has the following characteristics; it can occur on the surface or internally; it is associated with processing at too low a temperature; it is often caused by excessive working; and it creates straight or irregular cavities varying in size. How would it be identified or classified? Burst
