Influence of cold rolling reduction (65%-80% ) and annealing temperature (660-780 ℃ ) on structure
mechanical properties and formability of a Ti-IF steel (/% : 0.02C
0.012Si
0.10Mn
0.013P
0.011S
0.064Ti
0.0020N) has been studied by orthogonal experimental method. Test results show that with annealing at ≥ 700 ℃ the recrystallization of Ti-IF steel is basically completed t with reduction 75% and annealing at 700 °C the steel has better comprehensive properties i. e. yield strength 120 MPa
yield-tensile ratio 0.38
strain-hardening exponent n value 0.25 and plastic strain ratio r value 1.65.
