随等温时间的延长,小颗粒碳化物呈减少趋势,大颗粒呈增多趋势。碳化物的平均直径和长宽比随等温时间的延长而增大,而碳化物数量基本呈减少趋势。
With the prolongation of isothermal time, the small particle carbides decrease and the large particles increase. The average diameter and aspect ratio of carbides increase with the prolongation of isothermal time, while the number of carbides basically decreases.
