摘要

采用背散射衍射技术(EBSD)研究了3.13 mm热轧板的冷轧压下量(65%~80%)和再结晶退火温度(660~780℃)对0.64~1.10 mm Ti-IF钢冷轧板(/%:0.02C、0.01Si、0.10Mn、0.013P、0.011S、0.064 Ti、0.028Al、0.002 0N)的织构和成型性能应变硬化指数(n)、塑性应变比(r)的影响。结果表明

Ti-IF钢冷轧板在冷轧压下率为75%时{111}织构含量最大

成型性能最佳;在740℃以下再结晶退火时材料{111}<110>织构含量高

高于740℃时材料{111}<112>织构含量高;在660~780℃再结晶退火随温度增高

材料{111}织构含量增加

成型性能提高。

Abstract

The influence of cold rolling reduction (65% ~ 80% ) of 3. 13 mm hot rolled plate and recrystallization annealing temperature (660 ~ 780 °C ) on texture and formability-train-hardening exponent (n) and plastic stain ratio (r) of 0.64~1. 10 mm cold rolled sheet of Ti-IF steel (/% : 0.02C

0.01 Si

0. 10Mn

0.013P

0.011S

0.064Ti

0. 028Al

0.002 0N) has been studied by electro backscattering diffraction method. Results show that with cold rolling reduction 75% the {111} texture content in Ti-IF cold rolled sheet is highest and the formability is optimum ； with recrystallization annealing at ≤740 ℃ the {111} < 110 > texture content in material is high and with annealing at more than 740 ℃ the {111} < 112 > texture content in material is high ； and as recrystallization annealing at 660 ~780 °C

with rising annealing temperature the {111} texture content in material increases and the formability of material also increases.
