摘要
测定了螺纹钢在热轧、退火、正火状态下,码尺长度为2.5~62.5μm的分形维数和它们的自相似结构上界长度。表明在不同码尺范围,维数和上界不同,在10~62.5μm区间,维数高,强度低,塑性好。
We have measured the fractal dimension D and the upper length limit of self-imilar structure Lo of the screw steel under hot ?rolled, annealed and air cooled state respectively. The results show that the value of D as well as Lo varies with the testing size 1. We find that the greater the value of D, the greater the value of perc entageelongation (the lower the tensile strength) is when 1 is in the range of 10-62.5μm。
