Do you know the heat treatment modes of additively manufactured products of Inconel 718, which will lead to an increase in plastic properties (reduction area and ultimate elongation).
dear Дмитрий Оголихин
the following research reported a suggestion of time-temperature-transformation-diagram for IN 718. It has been proven that higher strain rates cause earlier precipitation and finer dispersion of the γ-phase.

If you used SLM, first of all do a stress relieve treatment for the as-printed part.
The suggestion of Mahmood appears okay although not significantly different from the traditional standard heat treatment procedure for IN718. In a study on Cobalt based supperalloy, (Effect of Process Optimization Parameters and Hot Isostatic Pressing on Microstructure and Hardness of Additive Manufacture Co-Cr Aerospace Alloy. - https://www.cwbgroup.org/association/research-papers ) Hot Isostatic Pressing was found to significantly improve strength (Hardness) of the Co Based Superalloy, aside from reducing defects associated with AM process.
