| Microstructure and Mechanical Properties of Ti-35V-15Cr-0.05C Nonburning Titanium Alloy |
| |
| 摘 要： | Ti-35V15Cr-0.05C is a new nonburning titanium alloy. The structural analyses show that the alloy consists of β phase and lath-like α phase distributed within β grains, and some titanium carbide particles appear at grain boundaries. Using dark field TEM method, it was also found that TiCr2 phase uniformly precipitates in α phase. After heat treatment at 900℃ for 15 min,equiaxed β phase of 60~ 80μm in diameter and lath-like α phase of 1-2% volume fraction were observed. This alloy possesses attractive mechanical properties.
