Paper Abstract

Miniaturized dogbone tensile specimens are used to determine mechanical properties when only a small amount of material is available. Because of the high surface to volume ratio, surface finishing becomes critical for specimens with diameters less than 2 mm. Barkhausen noise technique was used to characterize the machined surfaces of small diameter tensile specimens. Full surface scans were conducted using a new magnetization technique. The Barkhausen noise profile curves for several different analyzing frequencies were compared to those obtained on electro-polished specimens using correlation techniques in order to characterize the penetration depth of the surface treatment.
