为了研究硬化对铜沉淀物直径和密度的依赖性，在热老化铁铜合金中位错滑过铜沉淀物的拉伸试验期间进行了原位 TEM 观察。障碍物强度是根据位错的临界弯曲角 ψc 估算的。将原位 TEM 观测测量的位错线上的障碍物距离与 3DAP（三维原子探针）和 TEM 观测测量的数密度和直径进行比较。将基于临界弯曲角的硬化估计与传统拉伸试验获得的硬化估计进行了比较。
In order to investigate the dependence of hardening on copper precipitate diameter and density, in situ TEM observations during tensile tests of dislocation gliding through copper precipitates in thermally aged Fe–Cu alloys were performed. The obstacle strength has been estimated from the critical bow-out angle, ϕc, of dislocations. The obstacle distance on the dislocation line measured from in situ TEM observations were compared with number density and diameter measured by 3DAP (three dimensional atom probe) and TEM observation. A comparison is made between hardening estimation based on the critical bowing angles and those obtained from conventional tensile tests.
