Hydrogen and flakes in steel

Abstract

Flakes are special discontinuities in steel parts that have the form of silver-colored spots on fracture surfaces or thin hair-like cracks on a ground and etched template. They appear and grow after a considerable incubation period, often in the operation of the part, which makes them a dangerous defect. Depending on the dimensions, number, and position in the metal, flakes can decrease the toughness and ductility of steel to zero and reduce markedly the service life of steel parts and structures, causing unexpected and serious failures. The present review briefly generalizes recent works devoted to the formation of flakes in steel.
