The Engineers Post Types of Forging Defects [Their Causes & Remedies] PDF - The &#;&#;Flakes are forging defects caused by improper cooling of the forging product. Specifically, it is internal cracks in the forged parts that are caused by the quick cooling of the forged parts, which reduces the strength of the forged parts. This type of forging defect can be avoided when the forging product is properly cooled.
