Abstract

An overview of publications about advanced research in the field of development and application of titanium alloys is hereby provided. The importance of determination of low hydrogen concentration in titanium alloys is highlighted. The challenge for VIAM now is to develop new measurement procedures and manufacture reference materials (CRMs) with certified hydrogen content. Existing measurement procedures for determination of hydrogen content in Ti alloys are hereby overviewed. The experience of such method developing by using the RHEN-600 gas analyzer unit is considered in details – from the choice of the reference materials and unit pre-treatment method to metrological characteristics estimation. The developed measurement procedure for determination of hydrogen content in Ti alloys by fusion of reference material in inert gas (argon) is approved and included in the State Register.
