In this study, fine grains are achieved with weak texture of selective laser melted Inconel 718 (SLM IN718) if annealed within a narrow temperature range (1,070 ∼ 1,090 °C), while abnormal grain growth (AGG) is induced if annealed at temperature higher than that range, resulting in large matrix grai...
