【Abstract】 The improved method predicting anisotropy of plastic pro- perties in deep drawn steel plates was briefly introduced in this paper. The R(θ)-θ curves of some characteristic texture components have been calculated using the computer program written in FORTRAN-Ⅳ language. Discussion and comparison of the calculated results with the experimental ones show that the prediction procedure,as a whole is reliable and usable.Furthermore, the texture components and their volumes’percentage in some commercial deep drawn automobile steel sheets made in China were determined by quantitative texture analysis, and the R and ΔR values were further calculated by using the program and employing the measured data as constraint conditions. Results show that they are in accordance with the measured ones, and the analyzing procedure for prediction for anisotropy of plastic properties has been pr oved to be also efficient and satisfactory.更多还原
