چکیده انگلیسی
Introduction of compressive residual stress on the surface of dynamically loaded structural members improves the fatigue life. Oil jet peening is a new surface modification technique that can be potentially applied to introduce compressive residual stresses. Effect of oil jet peening on the surface modification and fatigue behavior of medium carbon steel, AISI 1040, is reported. The compressive residual stress on the surface of oil jet peened specimen was in the order of 332 MPa and the depth of compressive stress induced was about 50 μm. The surface hardness increased due to the oil jet peening. Oil jet peening improved the fatigue strength under cantilever-bending conditions to about 19% compared to unpeened specimens.
