The pinning effects of carbide particles on the grain growth of ferrite were studied in Fe-0.1C-0.0005B and Fe-0.1C-0.09V alloys. The number and size distribution of carbide particles were determined on multiple sections in distinction of grain facesm edges and corners. The numbers of particles in contact with each type of grain boundary site were several times greater than those calculated assuming random distribution. Taking this into account, the final grain size is predicted to be in fair agreement with measured ones.

在Fe-0.1C-0.0005B和Fe-0.1C-0.09V合金中，研究了碳化物颗粒对铁素体晶粒生长的钉住作用。在区分晶粒面、棱角的情况下，测定了多个断面上碳化物颗粒的数量和尺寸分布。每一种类型的晶界点所接触的粒子数比随机分布计算的粒子数大几倍。考虑到这一点，预测的最终晶粒尺寸与测量值基本一致。
