摘要：
In order to analyze superplasticity and diffusion bonding of Ti-22Al-24Nb, uniaxial tensile experiment at high temperature, vacuum diffusion bonding and superplastic forming were carried out based on Ti-22Al-24Nb alloy. The results show that Ti-22Al-24Nb has the best superplasticity under temperature of 960 degrees C and strain rate of 0.0005 s(-1); by observing the diffusion bonding interface by metallographic microscope and conducting shear strength tests, it finds that under temperature of 960 degrees C and holding time of 2 h, with the increase of pressure within certain limit, effect of diffusion bonding gets better; after superplastic forming, the box-shaped component fits the die well, wall thickness is well distributed in general, and it has enough tensile strength at room temperature and high temperature.
