  Chinaheoretical analyses show that the variation of wall thickness is in direct proportion to outer-diameter;

  inter-diameter;

  and (1+R_s)~(1/2) (Rs is sectional increase ratio of tube);

  the theoretical calculated results of wall thickness during tube dieless upsetting are very approximate to the experimental one. As the width of deformation field increases;

  both the variation of wall thickness and the derivative of wall thickness variation to width of deformation field (to/tf) reduce.;
