Abstract Scope |
Hot tearing is a well known casting and welding defect that negatively affects the mechanical properties of many alloys. Many tests exist for both casting and welding to assess hot tearing susceptibility of materials and processes. Hot tearing is also an issue observed in additive manufacturing (AM), yet no susceptibility tests currently exist. Consequently, assessment of hot tearing in AM is currently subjective; the extent of cracking is assessed qualitatively, or in cases where cracks are quantified, there is no consistency among the research parameters. In this presentation, we will review existing crack tests for casting and welding and discuss their potential relevance to AM. This literature review revealed factors that are common among existing tests, as well as unique concepts among individual tests. These concepts will be related to AM to assess their applicability to the development of a standardized benchmark specimen to evaluate hot tearing in AM. |
