Scope Unique property characteristics, temperature resistance and resistance to aggressive environment of Ni-based super alloys make this class of materials uniquely qualified for applications involving extreme service condition, i.e., high temperature or aggressive environment. They have been a material of choice for many aerospace applications, including high temperature sections of jet engines. Additive Manufacturing opens new opportunities and the possibility of increasing performance of the components made from these alloys, which could not be attained with any other conventional manufacturing technologies. The AM components undergo, however, a very unique processing, which typically involves localized melting, rapid solidification and multiple heating-cooling cycles. All these steps provide conditions for producing microstructure and material’s properties that may differ from those obtained in materials that were produced by conventional processing. Additive Manufacturing continues to attract attention of professional communities including research, design, and process engineers. However, more research needs to be done before a better understanding of the capabilities of these processes and their effects on the materials’ microstructure are developed. The main purpose of this symposium is to provide a forum for presenting the results of work related to the investigation of the effects of additive manufacturing process parameters on the microstructure and properties of the components and products made from Ni-based alloys.
