摘要
除了组织形态控制之外,晶粒细化是提高管线钢强韧性的关键环节.随着管线钢向着高钢级发展,其晶粒度级别增加,尤其是X100管线钢的晶粒细化现象更为突出.此外,系列管线钢的有效晶粒是不同的,各管线钢的有效晶粒尺寸并没有按照钢级的高低进行有序分布,有效晶粒尺寸和力学性能的差异密切相关.
Beside control of the shape of microstructure, the grain refinement is another key factor to im~ As the development of line pipe, the grain refinement is obviously it the effective grain size of series pipeline are different. The effected orderly according to the grade of steels. Effective grain size can and corresponding to the small difference of mechanical properties
