Web25 de jan. de 2024 · Large components, for instance in the energy industry, mining and heavy machinery, are produced from high weight cast as ingots followed by open-die forging. Besides achieving a certain final geometry and microstructure, one of the main objectives during the forging process is the elimination of casting defects, like voids … Web4 de jan. de 2024 · This type of forging defect arises when areas within the product have not been fully filled, as the name implies. The main reasons for this defect are poor die design, poor raw material, and poor forging techniques. It can also be caused by poor die layout and less raw fabric or poor heating.

WebOccasionally, internal defects are found in open die forgings. The potential origins of these internal fractures can be 1) unconsolidated solidification shrinkage voids, 2) heating or forging "bursts", or 3) hydrogen "flaking". Defect surfaces are often examined in a scanning electron microscope (SEM) to aid to determine their root cause.
