Alloying titanium alloys with rare-earth metals

Abstract

Fundamental research on the microalloying of high-strength, ultrastrong, and high-temperature titanium alloys with rare-earth metals permits the development of VT23-1 and VT43-1 (α + β) alloys and VT19-1 β alloy. In mechanical, physical, and economic characteristics, the VT38 pseudo-α alloy, also created in this research, outperforms β-21S alloy (produced in the United States).
