我们表明，亚微米尺寸的支持铁颗粒的硬质金刚石尖端的塑性变形加速其形状在退火过程中的演变在880摄氏度的温度下，低于α-γ转变温度。采用平衡的统计标准，我们发现平衡的α-Fe晶体显示{011}，{001}，{111}和{112}面。发现α-Fe对蓝宝石基面的粘附功为23 J/m（2）。(C)2016爱思唯尔有限公司版权所有
We demonstrate that plastic deformation of submicrometer-size supported Fe particles by a hard diamond tip accelerates the evolution of their shape during annealing at the temperature of 880 degrees C, below the alpha-gamma transformation temperature. Employing statistical criteria for equilibration, we found that equilibrated alpha-Fe crystals exhibit {011}, {001}, {111}, and {112} facets. The work of adhesion of alpha-Fe to the basal plane of sapphire was found to be 23 J/m(2). (C) 2016 Elsevier Ltd. All rights reserved.
