Rehbinder effect explained

In physics, the Rehbinder effect is the reduction in the hardness and ductility of a material, particularly metals, by a surfactant film.^[1] The effect is named for Soviet scientist,^{[2] [3]} who discovered the effect in 1928.^[4]

A proposed explanation for this effect is the disruption of surface oxide films, and the reduction of surface energy by surfactants.^{[1] [5]}

The effect is of particular importance in machining, as lubricants reduce cutting forces.^[6]
