1.1 ,This standard specifies the requirements for thermal post-processing of parts produced via metal powder bed fusion to achieve the required material properties and microstructure to meet engineering requirements. This standard is intended to be referenced by Material Part Property specifications for powder bed fusion. Currently, this standard includes thermal post-processing for the materials including titanium alloys, cobalt 28 chromium 6 molybdenum, alloy UNS N07718, alloy UNS N06625, alloy, UNS 31603 and AlSi10Mg. This specification will be updated as new powder bed fusion material heat treatments are developed.
