ASTM International has announced announces F3301-18, a standard specification for thermal post-processing metal parts made via powder bed fusion. 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, the organization says. 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 following materials: titanium alloys, cobalt 28 chromium 6 molybdenum, UNS N07718, UNS N06625, UNS 31603, and AlSi10Mg. This specification will be updated as new powder-bed fusion material heat treatments are developed, according to ASTM.
