The effect of coiling temperatures on the evolution of texture in Ti-IF steel during ferritic hot rolling, cold rolling and annealing was studied. It was found that texture evolution at high temperature coiling is absolutely different from that at low temperature one. The hot band texture includes a strong α-fiber as well as a weak γ-fiber after ferritic hot rolling and low temperature coiling. Both of them intensify after cold rolling and a γ-fiber with peak at {111}<112> is the main texture of annealed samples. However, the main component of the hot band texture after high temperature coiling is γ-fiber. After cold rolling, the intensity of γ texturereduces; α fiber (except {111} <110> component) intensifies and a strong and well-proportioned γ-fiber forms in the annealed samples.

基于CSP工艺，通过对X65和X65Re管线钢进行热模拟试验，分析稀土铈元素细化X65管线钢组织晶粒的机理。试验结果表明，稀土铈能抑制X65管线钢再结晶的发生，在热变形过程中有利于应变能累积，在连续多道次变形后，所累积的应变能为变形诱导铁素体相转变提供驱动力，进而细化了组织晶粒。
