| description | Titanium alloys used for rotating parts of aeroplanes must meet the strict standards of quality, so that it is required to demonstrate that electron beam melting is capable of producing defects-free ingots. However, complete elimination by dissolution of low density inclusions (LDI) having high nitrogen content would be difficult, so that a new way of eliminating LDI was needed. Therefore, control of a state of the molten titanium flow with the aide of Marangoni flow induced by electron beam has been studied, and the effects on eliminating LDI have been verified. |
