Development of certified reference materials for titanium and titanium alloy composition

Eroshkin S.G., Shvetsova A.N.
Abstract

Certified reference materials (CRMs) of titanium grades VT1-0 and VT1-00, as well as of titanium alloys VT6, VT6ch, OT4-0, OT4-1, and OT4 have been developed. A batch of CRM material has been manufactured. Homogeneity studies and stability studies of the CRM material have been carried out using the accelerated aging method. The certified values of the CRMs and the relative error of the certified values have been determined. The CRM material has been tested for type approval, and the CRM types have been approved. A test program for serial production of CRMs of titanium and titanium alloys has been developed.

Keywords
