| 總結: | Title screen The structure of the titanium alloy Ti-6Al-4V manufactured by electron-beam melting is shown to be represented by initial [beta]-phase grains more than 40 [mu]m in size; the internal volume of the grains is filled with [alpha]-phase precipitates in the form of plates. The average size of the [alpha] plates is 1.6, 2, and 5 [mu]m at beam currents of 2, 2.5, and 3 mA, respectively. In situ X-ray diffractometry using synchrotron radiation shows that the phase transitions in the titanium alloy are divided into three main stages during hydrogenation to a concentration of 0.6 wt % at a temperature of 650°C and a pressure of 1 atm. An increase in the beam current from 2 to 3 mA does not significantly affect the phase composition of the alloy. During hydrogenation, the growth rate of the volume concentration of the [beta] phase is lower at a higher beam current. This indicates a decrease in the rate of hydrogen absorption with increasing beam current, which is associated with an increase in the size of [alpha] plates.
