ON MECHANISM OF HYDROGEN INTERACTION WITH TITANIUM AT PRESSURES UP TO 150 Mpa

摘要

The investigation of hydrogen interaction with titanium has been carried out at temperatures 300, 373, 473 K and pressures up to 150 MPa as in conditions of all-side compression as when stretching stresses up to 0.9 of yield strength. As a result of carried out investigations at temperature 300 K and pressure up to 150 MPa, the hydrogen penetration into titanium was not found out even when stretching stresses up to 0.9 of yield strength were applied to a specimen. With increasing temperature up to 373 K hydrogen occlusion into titanium takes place, this effect sharply increases when in case of applying stretching stresses to a specimen. Sharp increase of hydrogen consumption by titanium takes place at temperature 473 K and higher, however in this conditions no stress influence can be found. This work says about mechanism of temperature and stresses influence on hydrogen penetration into titanium.
