对机械球磨珠光体钢制备的纳米晶铁素体的三维原子探针分析表明，碳原子强烈偏聚在晶界，碳在纳米晶铁素体中的固溶约为1.0at.%。400℃退火后，碳从晶界排出，渗碳体在晶界析出，纳米晶组织仍保持不变。(C)2004年Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Three-dimensional atom probe analysis of the nanocrystalline ferrite produced by mechanically milling pearlitic steel indicated that carbon atoms are strongly segregated at the grain boundaries, and approximately 1.0 at.% carbon are dissolved in the nanocrystalline ferrite. Annealing at 400degreesC led to the rejection of carbon from the grains and the precipitation of cementite at the grain boundaries, while the nanocrystalline microstructure was retained.
