Paper Title:
Effect of Quenching Temperature on Microstructures and Tensile Properties of PM Ti-23Al-17Nb Alloy
  Abstract

After treated with different quenching processes near transition temperature of orthorhombic phase, PM Ti-23Al-17Nb alloys with different microstructures were obtained. Microstructures of the alloy were observed by optical microscope, and tensile properties were also tested. In order to analyze the relationship between microstructures and tensile properties at room temperature, fractures of broken test bars obtained in tensile tests were characterized by SEM. The results show that quenching process below transition temperature of orthorhombic phase has few effects on improvement of size and morphology of crystal grain. However, it may lead to an abnormal growth of partial crystal grain, which results in low tensile strength and poor ductility; Quenching process above transition temperature of orthorhombic phase can cause recrystallization of B2 phase, which make a remarkably improvement on size and morphology of crystal grain. Moreover, the alloy performs the max tensile strength of 1026 MPa and the max ductility of 5.8% after quenched at the temperature of 1020
