钢中硫化物形貌对钢的切削性能及等向性能有重大影响。根据Sims分类法,硫化物铸态形貌有三类:Ⅰ类呈球状,任意分布;Ⅱ类呈短棒状,沿晶界分布;Ⅲ类呈规则块状,任意分布。可见硫化物铸态形貌是不规则的。Mandelbrot提出的分形几何已被用来描述
Sulfide morphology in steel has a significant effect on the machinability and isotropism of steel. According to the Sims classification, there are three types of as-cast morphologies of sulfides: Class I is spherical and randomly distributed; Class II is short rod-shaped and distributed along grain boundaries; Class III is regular and randomly distributed. Shows sulfide as-cast morphology is irregular. Fractal geometry proposed by Mandelbrot has been used to describe
