INFLUENCE OF REHEATING TEMPERATURE AND COLD ROLLING REDUCTION DEGREE ON TEXTURE, R-VALUE AND ΔR-VALUE OF TI IF STEEL

摘要

The effect of reheating temperature and cold rolling degree on texture, r-value and Δr-value of a Ti IF steel were investigated. r-value increases up to 90% of cold roling reduction, Δr value becomes zero at 92%. Earing changes from 4 ear to 6 ear behaviour. The texture changes from fibre type to peak type.
