| Abstract Scope |
Laser and electron beam technologies are the most common technologies used for production of metallic parts using additive technology. Although very versatile, variation in the process parameters can result in variety of grain sizes from equiaxed to columnar grains formed in a preferred orientation and a whole range of grain sizes which then results in unexpected mechanical behavior. This presentation summarizes our recent findings on the grain formation, size and orientation for multiple metals during this complex process. The effect of process parameters on the final micro-structure is discussed. Micro-scale mechanisms of plastic deformation and impact of columnar grain formation on these mechanisms are presented. New ideas on utilizing the ability to tailor the grain formation during the process in direction for designing new materials and micro-structures are presented. |
