Vv. Levitin et al., INFLUENCE OF CYCLIC STRESSES UPON THE ELECTRONIC WORK FUNCTION FOR THE METAL-SURFACE, Solid state communications, 92(12), 1994, pp. 973-976
The work function was measured for surfaces of Ti and Al specimens und
er the influence of alternating stresses. A decrease of the work funct
ion preceded a fracture. Moreover, the drop of the work function was a
lso observed on the side of specimens which was opposite to that where
a microscopic crack would be formed. It is concluded that the value o
f the work function is probably related to the dislocation multiplicat
ion as well as to the formation of new surfaces.
