Abstract : Selected LiF crystals with initial dislocation densities of approximately 10 to the 5th power/sq cm were subjected to applied rolling loads ranging from 25 to 500 gms. Measurements of the surface width of the deformed zone trace and the dislocation density within the deformed zone were made after loading. Tabulated results indicate the surface deformation characteristics imposed by rolling loads. In order to study the effects of various fluids on the torsional fatigue life of 52100 tool steel, a machine and a specimen were designed. The machine consists of a lever arm which is attached to one end of the specimen perpendicular to the specimen axis. (Author)
