| Abstract: | In this paper,the drawing theoretical calibration curves by computer for determina-tion friction coefficient using upset forging of rings are given.It is explored first thatthe application of the ring upset method for tool-die steel under the condition of super-plastic forming.Under the condition of superplastic deformation,friction coefficients ofsome lubrication in common use are measured,and the factors which influrence on fric-tion coefficient are analysed and discussed. |
