| Popis: | Ti-based alloys are finding ever-increasing applications in biomaterials due to their excellent mechanical, physical and biological performance. Ti-6Al-6Mo shows good hot workability, mechanical behavior and corrosion- resistant. Therefore, this alloy has a potential used as a biomaterial implant. The effect of various pre-heating time and 88 % reduction of the hot rolling process was conducted to Ti-6Al-6Mo alloy. The study aim is to investigate the characteristic of α phase in Ti-6Al-6Mo alloy after pre-heating and heavy hot rolling. The homogenized Ti-6Al-6Mo alloy was pre- heated at 1000 °C with a various holding time of 15, 30, and 60 min and followed by 88 % hot rolling. Microstructures of this alloy observed by optical microscopy (OM) and scanning electron microscopy (SEM). The hardness of Ti-6Al-6Mo alloy after the process was examined using Rockwell hardness testing machine scale C. The results showed the α phase characteristic was changed its morphology. The α phase leading to a globular structure and it’s increasing the hardness due to increasing pre-heating time. |
