Nondestructive Detection of Hydrides and Alpha-Case in Titanium Alloys
Titanium and titanium alloys have a strong affinity for the elements hydrogen and oxygen. Hydrogen can be absorbed at elevated temperatures from water vapor, oil, or other hydrocarbons, and hydrogen atmospheres used for furnace or induction brazing. Current specifications limit hydrogen content to 50 to 150 ppm depending on the alloy and mill product. Above these contents, hydrides may form which can embrittle titanium alloys and cause cracking.
