Positive roles of hydrogen in titanium alloys

Chapter


Abstract


  • © 2017 by Nova Science Publishers, Inc.Hydrogen is usually regarded as an impurity element in titanium alloys because even relatively low concentrations of hydrogen can lead to material failure if hydrogen is trapped around structural defects and local concentrations exceed a critical value. However, positive roles of hydrogen in the production and processing of titanium alloys can also be utilised if appropriate technologies can be developed based on the unique reversible reaction of hydrogen with titanium. This chapter presents a commentary on the positive roles of hydrogen in titanium alloys in the aspects of microstructural refinement, hot workability, superplasticity, powder metallurgy, hydrogen storage, mechanical properties, wear resistance, welding, bonding, machining and deoxidation, with the purpose of helping readers to obtain a quick method of the special and effective hydrogen treatment technology of titanium alloys.
