Development of voltage fields in titanium VT1-0 while forming a Thin Wedge-Shaped Twin

Abstract

In the selected treatment modes, a thin wedge-shaped twin was observed, it passed through a section of the crystal with a weak concentration of visible defects. Additional etching of the titanium film revealed an ordered arrangement of dislocations with contrast that appeared on the surface inside the circular sites, which are the stacking faults inside the dislocation loop. The authors provide an explanation of the formation of stacking faults using the detected oscillating contrasts of the faults that are close to the surface. The voltage fields around the wedge-shaped twin, which were constructed with the use of computer simulation, made it possible to determine the value of the elastic stress when it comes into contact with the stopper.
