Additive manufacturing laser-directed energy deposition Technical Specifications for Titanium Alloy Parts

1 Scope

GB/T 47005-2026 is the Chinese national standard covering titanium parts built by blowing powder into a laser melt pool - the feedstock, the atmosphere, the build and its thermal history, the anisotropy of the deposited metal, the heat treatment and hot isostatic pressing, and the inspection of a part whose microstructure was created layer by layer. It is the process used to repair and to grow large aerospace titanium structures. First edition. It was issued on 28 January 2026 and has been in force since 1 August 2026, as a first edition. The document is under the responsibility of the China Machinery Industry Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the technical requirements, test methods, inspection rules, and delivery preparations for laser-directed energy deposition of titanium alloy parts. This document applies to the trial production and manufacturing of TA15, TC4, TC11, TC17, TC18, and TC21 titanium alloy parts produced by laser-directed energy deposition. and acceptance.
