Abstract

Abstract

Hot rolled IF steel was used to study the effect of cold reduction ratio on the microstructure textures and mechanical properties of Ti-IF and Ti+Nb-IF steel after batch annealing processes.The results showed that recrystallization of the IF steels was rudimentarily finished after batch annealing,the grain shape is pancake;and the grain size diminishes as the cold reduction ratio was increased;the strain hardening exponent n value was gradually reduced.The plastic strain ratio value(r_90°) of Ti+Nb-IF steel reached the maximum with the higher carbon content and cold reduction ratio of 70%,or with the lower carbon content and cold reduction ratio of 80%;the plastic strain ratio value(r_90°) of Ti-IF steel reached the maximum with cold reduction ratio of 70%;however,when the cold reduction ratio was increased,the textures of IF steel was stronger,then the {223}<110>、{114}<110>and {111} textures of lower cold reduction ratio were changed to {223}<110>、{111}<110>and {114}<110> textures of higher cold reduction ratio,and the textures trend toward {111} texture.
