• Site specific control of crystallographic grain orientation through electron beam additive manufacturing (2015, background): “Generally ignored has been the a priori control of the final microstructure distribution within AM parts by hardware manufacturers.(2,3) Recently though microstructure control within AM processes has become an area of increased interest.”
• Additive manufacturing of metallic components – Process, structure and properties (2018, background): “Thus, enhanced precipitation occurs in c regions close to eutectic products during repeated heating and cooling processes [348].”
• Knowledge of process-structure-property relationships to engineer better heat treatments for laser powder bed fusion additive manufactured Inconel 718 (2019, background): “These observations give direct evidence for the as-printed Ti and Nb segregation they hypothesized in observing solution-annealed AM-IN718 microstructures, and is consistent with previous reporting [17,21,57,68].”
• Anisotropy and heterogeneity of microstructure and mechanical properties in metal additive manufacturing: A critical review (2018, background): “Another study based on DED-built IN718 superalloy has also attributed the formation of precipitates to cause heterogeneity in hardness [13].”
