摘要：
The ability of micro-cracks formation in high purity aluminum during electrochemical charging by hydrogen has been studied. The experiments revealed that the existence of a large size distribution of hydrogen bubbles on the surface (blisters) and under the surface obtaining during electrochemical charging can leads to micro-cracks formation in the absence of an external applied stress in aluminum samples. Transmission Electron microscopy (TEM) samples after electrochemically charging showed micro-cracks with typical ductile mode of fracture.
