| 초록 | Heating experiments using the Ti-3Al-2.5V tube materials in a vacuum furnace have been performed to investigate a pertinent range of working temperatures and holding times for the development of the successive or simultaneous operation of superplastic hydroforming and diffusion bonding. The specimens were heated at $820^{ circ}C$ , $870^{ circ}C$ and $920^{ circ}C$ respectively. Holding times at each temperature were varied up to 4 hours. Holding times longer than 1 hour were selected to consider the diffusion bonding process after or during the hydroforming process in the superplastic state. Grain sizes were varied from $5.7{ mu}m$ of the as-received tube to $9.2{ mu}m$ after heating at $870^{ circ}C/4hours$ . Homogeneus granular microstructures could be maintained up to $870^{ circ}C$ , while microstructures at $920^{ circ}C$ showed no more granular type. |
