The Microstructure and Mechanical Properties of High-Strength and High-Toughness Titanium Alloy BTi-6554 Bar

Abstract:

This paper is concert about the mechanical property of high strength and high toughness titanium alloy BTi-6554 (Ti-6Cr-5Mo-5V-4Al) bars. The results show that: in β-phase zone solid solution + aging treatment condition, the strength and fracture toughness of the alloy at room temperature can reach a higher level while inα+β)-phase solution + aging treatment condition, the plastic property is relatively high. Compared with Ti-1023 and VT22 alloy bars produced by the similar processing procedure, the alloy shows improved properties combined in strength and toughness. BTi-6554 is a new type of titanium alloy with high structural efficiency, and has a good prospect for commercial and application.
