Abstract

The effects of solution treatment on the microstructure and mechanical properties of Ti‐22Al‐25Nb alloy are investigated. Numerous equiaxed α2 particles distribute in a B2 matrix after solution treatment in the α2 + B2 region. The growth rate of the B2 grain increases with solution temperature and decreases with increasing holding time. When the solution temperature is lower than B2‐transus, it is seen that both the strength and ductility decrease with increasing solution temperature and holding time. After being solution‐treated at a super‐transus temperature, the alloy with a fully B2 microstructure shows an ultralow elongation (∼5%) and a typical brittle fracture characteristic.
