High-density pulsed current: a review of its role in healing macrocracks in metals

Abstract

In the context of structural materials, the process of degradation and damage ultimately results in the formation of micro-cracks, which subsequently lead to the failure of the material in question. The reliability and service life of structural materials can be significantly increased if cracks are healed at the meso- and micro-level. It is therefore of great interest to researchers to study defect healing in various materials. In particular, research on the use of strong pulsed electromagnetic fields to heal cracks and pores in conductive materials has been intensified recently. This paper presents an overview of research on healing macrocracks in metals by applying a strong pulsed electromagnetic field inducing a pulsed electric current in the material. It describes the methods and materials used in the experiments, as well as the results obtained.
