Sample Preparation of Titanium and Titanium Alloys
Titanium and titanium alloys usually adapt cooling mounting.
Heat mounting may can produce the hydrogen pollution and the metastable βphase will decompose because the hydrogen in the mounting material may diffuse into the sample in the hot state.Since the solubility of hydrogen in the α phase is extremely low, the solubility increases when the temperature rises, and the solubility decreases when cooling, resulting in the precipitation of tiny dispersed titanium hydrides.
