PROCESS FOR PRODUCING A MOULDED PIECE MADE FROM AN INTERMETALLIC GAMMA-TI-AL MATERIAL |
摘要 |
A shaped part or article of manufacture is formed of a selected gamma titanium aluminide alloy with outstanding mechanical properties which can be produced particularly economically. First, a semi-finished article is formed in a hot forming process with a degree of deformation of greater than 65%. Then the semi-finished article is shaped with the alloy being in a solid-liquid phase by applying mechanical forming forces during at least part of the shaping process. |
