    Abstract
  • Microstructure transformation in Ti-15V-3Cr-3Sn-3Al(TB5) titanium alloy during one way tensile test was studied in situ observations of the video microscope. The results show that the change of the microstructure of the titanium alloy in uniaxial tension is not obvious in the elastic stage, but according to the change of the slip bands in the microstructure it can be divided into three stages following with the increase of the deformation in the plastic stage. The three stages are the single slip, the multiple slip and the cross slip.Geometric hardening occurs from the single slip to the multiple slip in uniaxial tension, so the change of the grains slows down and the rotation range of the slip bands is smaller.
