| Abstract |
| Titanium and its alloys offer the highest strength, excellent corrosion resistance and the highest strength to weight, but their disadvantage is a higher cost. This study was made to obtain useful information on their high-strength properteis for designing beta type titanium alloys using the DV-Xα method. To lower prices low-cost elements (Mo, Al, Fe) were used. The Mechanical properties of these alloys are compared to commercial alloys in order to investigate the characteristics of the alloys. The results showed strength of the titanium alloys was somewhat higher (30-90 MPa) than conventional alloys. |
