Abstract

It is common knowledge that cast iron components may be affected by the presence of residual stresses. This often represents a serious threat, because residual stresses almost invariably cause a significant degradation of the most important material properties, such as reduced fracture toughness, accelerated stress corrosion, decreased fatigue resistance, and so on. In addition, they can also be responsible for undesirable shape distortions, which may compromise the fulfillment of geometrical tolerance requirements. As a consequence, a good understanding of what residual stresses are, how they form during the process, and how they can be prevented or at least minimized is indispensable to achieve the highest casting quality.
