Introducing gradient severe shot peening as a novel mechanical

WebJ443_201006. This SAE Recommended Practice provides uniform procedures for using the standard shot peening Almen strips reported in SAE J442. Standard Almen strips are used to establish saturation, determine intensity, monitor repeatability of the shot peening machine operations, and can be used to predict a desired result on a part. In metallurgy, peening is the process of working a metal's surface to improve its material properties, usually by mechanical means, such as hammer blows, by blasting with shot (shot peening), focusing light (laser peening), or in recent years, with water column impacts (water jet peening) and cavitation … See more Plastic deformation from peening induces a residual compressive stress in a peened surface, along with tensile stress in the interior. This stress state resembles the one seen in toughened glass, and is useful for similar reasons. See more Plastic deformation from peening can be useful in stretching the surface of an object. One common use of … See more Scythe and sickle blades have traditionally been sharpened by occasional peening followed by frequent honing in the field during use. A blade can be sharpened by reforming the … See more During construction of Barker Dam hydroelectric facilities in Colorado between 1908 and 1910, workers discovered that striking welds while … See more Cold working also serves to harden the material's surface. This makes cracks less likely to form at the surface and provides resistance to abrasion. When a metal undergoes strain hardening its yield strength increases but its ductility decreases. Strain … See more Hand peening may also be performed after welding to help relieve the tensile stresses that develop on cooling in the welded metal (as well as the surrounding base metal). The level of reduction in tensile stress is minimal and only occurs on or near to the weld … See more • Almen strip • Ball-peen hammer • Case hardening See more dry cracked skin around mouth
