The Microstructure and Mechanical Properties of Ti-6Al-4V Alloy Bar with a Large Diameter of 450 mm
A special thermomechanical process has been developed in order to improve the homogeneity of the microstructure and mechanical properties of Ti-6Al-4V alloy bar with a diameter of 450 mm for aerospace application. This study has investigated microstructure and mechanical properties on the large diameter bar. It has been found that the heavy section of the bar has uniform microstructure and mechanical properties, which can meet the specifications for Ti-6Al-4V alloy bar with a diameter of 300 mm, and ultrasonic inspection can meet the specification of ASM 2631 class A.
