チタン合金の現状と課題

抄録

Titanium alloy is the one of indispensable materials for aircraft structure, because of its low density, high strength, good heat resistance and good corrosion resistance. But the weight ratio of titanium alloys for aircraft structure is not so high, especially commercial aircraft. That main reason is high production cost depends on high material and processing cost. So many material and airflame manufacturer have been developed low cost material and process. This paper describes the recent trend of low cost technology that include our study
