In this paper, we discuss the impact that non-destructive 3D (x,y,z) and 4D (x,y,z,time) X-ray experimental methods have had on the understanding of recrystallization of deformed metals. Well-planned experiments on nucleation and grain boundary migration are reviewed with focus on information gained, which could not have been obtained by traditional 2D or destructive 3D methods. It has also been found that the 3D/4D X-ray measurements sometimes happen to reveal phenomena, which were not expected and therefore not planned to investigate. Examples of this are also reviewed here. Finally, the implications of the new findings for modelling of recrystallization are discussed, key experiments for the future are suggested and the needs for technique advancements are summarized, all seen from the recrystallization perspective.

在本文中，我们讨论了无损3D（x，y，z）和4D（x，y，z，time）X射线实验方法对了解变形金属的再结晶的影响。审查了计划周密的成核和晶界迁移实验，重点是获得的信息，而传统的2D或破坏性3D方法无法获得这些信息。还发现3D / 4D X射线测量有时会发现现象，这是无法预料的，​​因此没有计划进行调查。这里也回顾了一些例子。最后，讨论了新发现对重结晶建模的意义，提出了未来的关键实验，并总结了技术进步的需求，所有这些都从重结晶的角度来看。
